PhatMpk Posted November 5, 2009 Author Report Share Posted November 5, 2009 Replaced the 02 sensor back to AcDelco it doesnt want to shift unless i let off the gas, seems to lose power at WOT but gains more speed if i ease off the gas, or if i slowy ease into the gas it runs but still struggles to gain speed Quote Link to comment Share on other sites More sharing options...

PhatMpk Posted November 5, 2009 Author Report Share Posted November 5, 2009 ran it last night the boost gauge was reading +14 psi but still the same problems Quote Link to comment Share on other sites More sharing options...
pontiac6ksteawd Posted November 6, 2009 Report Share Posted November 6, 2009 Computer reset and Idle relearn for the new sensor, then see what happens. Also, your new O2 sensor, what color is the wire? Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted November 30, 2009 Author Report Share Posted November 30, 2009 Purple wire from the 02, reset the computer, now my boost guage is more accurate than it was when it wants to work, engine runs fine at low speeds, when im in forth gear on the freeway the engine is really knocking real bad, 1-2-3 gears still wants to really struggle to gain power after 3,000 rpms, when let it idle, my lights get kinda dim at night especially when the fan kicks on, the lights brighten up when i gain some speed, it seems to want to run a little better after i unhooked my 4,000 watt stero Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 3, 2009 Author Report Share Posted December 3, 2009 Installed that check valve on the vac modulator today, also found that maybe one of my spark plug wires came loose from one of the coils, but it was caked with die electric grease , runs perfect now on top end, shifts better than it ever has 5,500 rpms, engine still wobbles when i ease on the throttle in 4th gear thinking this must just be my upper motor mounts goin bad again Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 11, 2009 Author Report Share Posted December 11, 2009 ok symptoms are coming back a little bit, the spark seems to break up at high rpms again, especially when im in forth gear just ideling down the freeway, seems to get worse the lower the tank is on gas, I reused the old fuel pump pulsator when i replaced my fuel pump and used the new larger O-ring for the fuel tank lid that came with the pump, seems to hold presssure ok whenever i go to fill it up pressure does release only after running it for while, I have one new coil pack that im going to try and doctor tranny instant shudder fix Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted December 11, 2009 Report Share Posted December 11, 2009 I don't know much about TGP, but I was going to suggest the coilpacks. What about the ECM? Possibility of it taking a shit, or possibly a bad ground to it? Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted December 11, 2009 Report Share Posted December 11, 2009 doctor tranny instant shudder fix? I should have used that to instantly fix the broken band in my transmission! scammers. I would not support that brand by buying it. knowing they bank on false hope. and yeah, the coil packs. all three and a new ICM. all AC Delco if possible. you may look into getting a smaller starter to make thing easier when doing the ICM. take off the big stock starter and there is the lower bolt wide open. just make sure and torque all three back down with copper antiseize and you will have a good ground and no more worries. two of them vibrated loose on my red tgp (or someone did not know how to remove it all the way). also the starter power wire nut had wiggled loose. AND the CKS bolt was loose. which a good signal is only produced correctly at proper clearances to the crank. Quote Link to comment Share on other sites More sharing options...

I would not support that brand by buying it. knowing they bank on false hope. That stuff is intended to help with torque converter shudder and it does actually help somewhat. I know people that have had vehicles w/ converters that would slip + shudder pretty bad and it stopped them from doing so for a period of time. They used that stuff until they could afford to replace the converters... Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted December 12, 2009 Report Share Posted December 12, 2009 how do you diagnose torque converter studder? and what is the cause of this? Quote Link to comment Share on other sites More sharing options...
Jonpro03 Posted December 12, 2009 Report Share Posted December 12, 2009 Wait, did you install 24lb/hr injectors? I thought tgp's came with 22lb/hr. Would that be the problem? Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 13, 2009 Author Report Share Posted December 13, 2009 I put the other injectors back in it, replaced all six plugs with acdelco .45 gap and it doesnt run on the freeway again Quote Link to comment Share on other sites More sharing options...
Addicted To Boost Posted December 13, 2009 Report Share Posted December 13, 2009 Regap them at .30" and it should run better. Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 13, 2009 Author Report Share Posted December 13, 2009 Thanks thats what I was thinking since i did that with those bosch plugs and it run much better but spark still breaks up at low throttle in forth gear, I unhooked my stereo, and if I ease on the throttle it will take off, If I put it to the floor seems to flood imediately, would a low battery cause this as well? My battery dies ike twice a year when im running my audiobahn set up, if all else fails then coil packs then ICM Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 13, 2009 Author Report Share Posted December 13, 2009 Can any1 please walk me through changing the coil packs and ICM It looks as if there is a pack of wire running in front of the bottom bolts for the coils cant seems to get a socket in there Quote Link to comment Share on other sites More sharing options...
pontiac6ksteawd Posted December 13, 2009 Report Share Posted December 13, 2009 That wire pack, is your main hot cable from your starter!! Make sure you disconnect your battery befor going any further! Once you get the battery disconnected, you could force the socket in there (its what I do cause I am lazy), or you could remove the wire from the starter, do your work, and reconnect your wire.

God ya disconnect the battery. Last time I swapped icm I grounded the starter wire on oil or coolant line from turbo, cant remember which. Sucked... Each coil has two bolts top and bottom. Once you get all 6 out the ICM will come right off. Quote Link to comment Share on other sites More sharing options...

PhatMpk Posted December 21, 2009 Author Report Share Posted December 21, 2009 Yes they are 0.030 seemed to run better with bosch goldplus gapped to .030 would start good, idle, good and would run all the way to fourth gear then would seem to lose power while accelerating at about 50-55 put acdelco plugs in at .045, ran like in the video, hooked my stereo up with capacitor, can symtpoms seemed to disappear, took in on 1 hour trip , the next day ran just like in the video regapped the acdelco plugs to .030 with no improvement stripped one of the threads on the front left plug on the head chased the thread seems to hold now starts good idles good, runs good only up to 3,000 rpms Quote Link to comment Share on other sites More sharing options...
PhatMpk Posted December 22, 2009 Author Report Share Posted December 22, 2009 killinprixs: 7mm ? if so they burn right up, may work for 2-3 months but the misfiring will come back eventually, get like accel 8mm or MSD wires. also like i said if your positive its not the plugs/wires/coils/sensors/fuel pump/regulator/filter the only thing left is the injectors, seeing how you already replaced 2 others might be bad. I just replaced a set of injectors that were brand new only put on 2000 miles with them, had bad missfiring and boost problems, all injectors TESTED good but as soon as i changed them, all problems went away and car ran perfectly normal again. Even tho the injectors were new, one prematurely malfunctioned and the car ran like ass. I was chasing everything on that dam car until i had no other choice than to replace them ALL. Just goes to show when you ohm injectors it doesnt mean that they are physically working. Everythig else checked out like , compression perfect, fuel pressure 40#+, brand new ignition components, all sensors new, swaped ECM/ chips, fuel regulator. just took a look everything is dark as can be, no sparks jumping anywhere I can see, 7mm wires, maybe injectors are going bad as there are four original ones, 1 yellowtop, and 1 gp sorensen, I have the front three injectors stock, and the back three are 1 stock 1 yellowtop, n 1 gp, boost guauge seems to show +13 now but struggles above 3k, all the sensors seem to be working correctly except my oil pressure sending unit doesnt seem to be working as the guauge on the dash shows the pressure needle all the way up Quote Link to comment Share on other sites More sharing options...
