z34_nut Posted January 8, 2006 Report Share Posted January 8, 2006 I know my '93 auto had no problem getting the tires to spin from a stop....anyway... Don't forget about your fuel delivery system. A bad fuel filter and injectors are also a very commen problem for the "bog" that your talking about. Quote Link to comment Share on other sites More sharing options...
birdman Posted January 8, 2006 Author Report Share Posted January 8, 2006 well i replaced the fuel filter and im pretty sure the injectors are bad because they load up the cylinder so the first time i start it each day it runs rough for a min or two. ive got a set of 95's in the trunk and im sendin them out to get rebuilt and stickin those in when spring gets here.

birdman Posted January 8, 2006 Author Report Share Posted January 8, 2006 just had another thought, ive been thinking it could be an o2 sensor but ive heard that the ecm dosnt use it when at WOT, can anyone confirm that? thanks. Quote Link to comment Share on other sites More sharing options...
jeremy Posted January 8, 2006 Report Share Posted January 8, 2006 im pretty sure the injectors are bad I wouldn't even bother to try to troubleshoot this problem any further until you get good injectors installed Quote Link to comment Share on other sites More sharing options...
birdman Posted January 8, 2006 Author Report Share Posted January 8, 2006 well i know what your saying but i dont see why anywhere past 2/3 throttle is like on and off, you go too far down=slow, let up a little=go. just dosnt seem like leaky injectors would cause that, mabey im wrong though Quote Link to comment Share on other sites More sharing options...
Prospeeder Posted January 8, 2006 Report Share Posted January 8, 2006 too much gas = Loss of power Quote Link to comment Share on other sites More sharing options...
jeremy Posted January 8, 2006 Report Share Posted January 8, 2006 you go too far down=slow, let up a little=go sounds like it could possibly be clogged injectors Quote Link to comment Share on other sites More sharing options...
birdman Posted January 8, 2006 Author Report Share Posted January 8, 2006 yea, but its not like a progressive thing, literally its like mabey a 1/2 inch of pedal past 2/3 throttle just sucks. Quote Link to comment Share on other sites More sharing options...
z34_nut Posted January 9, 2006 Report Share Posted January 9, 2006 Just do it man...definatly one of the two..plugs, or injectors...w/o a doubt... EDIT: Fuck...Have you checked your Timing Belt reciently?? Quote Link to comment Share on other sites More sharing options...
SigEpCutlass Posted January 9, 2006 Report Share Posted January 9, 2006 Try running some heavy duty fuel system cleaner through it. My local GM dealership reccomended Chevron's Techron fuel system cleaner. It was about $13 at my local parts store. Maybe that'll help you out a bit with those injectors?

joey b Posted January 9, 2006 Report Share Posted January 9, 2006 my old 3.4 had 95K on it and couldn't spin the tires. It isn't completely uncommon for 3.4's to have a hard time getting a nice squawk. Hell my 97 with only 30K doesn't even burn em up too well. Top end cleaner, fuel filter, fuel injectors, all mentioned previously will probably help that a lot. Yes, over time the timing belt can stretch and that will also not help you at all. And DO NOT do the 13 degree cam retard. If people would actually read up on that they would know that it hurts low end torque very badly.

gp90se Posted January 9, 2006 Report Share Posted January 9, 2006 I can say how I got my 3.1's injectors 2 quiet down/clean them out, but I cannot recommend it, it *COULD* cause damage: With that said, Drive the car down to 1/4 of a tank or just below, put in 1/2 a bottle of seafoam into the gas. Drive 10 miles or so to make sure the mixture gets into the injectors and let it sit all night. Let it warm up next day and drive it SLOWLY to the gas station, your motor might ping at higher RPMS. Put in $10 of super in, drive it slowly for another 2-3 miles and then continue to drive it regularly. I was able to clear up my injector ticking that way.

birdman Posted January 9, 2006 Author Report Share Posted January 9, 2006 i did the cheveron and my timing belt look ok, at least its still the correct width, im planning on getting the timing tool and doing a 6* 6*, ive heard the dose a little for low end.

AWeb80 Posted January 10, 2006 Report Share Posted January 10, 2006 <-- Has absolutely no problem lighting up his front tires. Ya....i was good at it too..... Quote Link to comment Share on other sites More sharing options...
chadz34 Posted January 10, 2006 Report Share Posted January 10, 2006 there kinda like that, they make all there power at 4k-5k+ no low end, most guys cant spin them from a stop, unless they have some shitty tires again, RESEACH MAN, you sound like a tool AGAIN talking about a subject you know little about. My LQ1 will roast the tires from a stand still thru 2ed gear on dry pavement with good tires (but my lq1 isnt stock). threefours old lumina, BONE STOCK with 90k would light them up from a standstill with the press of the gas. Tonys lumina doesnt seem to have any problems spinning them either. Sounds like your car could use a good top end cleaning (pull the plenum off and scrub it), run 1/2 a can of seafoam or cleens thru it after, set of delco plugs, new o2 and a set of wires if needed. your bogging might be from an intake leak, so if you have the time, tackle that. Good luck, a healthy running LQ1 shouldnt have a hard time spinning them up. If you still have problems after getting it running right, the 13 degree timing mod will help ya bottom end out. I find that hard to belive A stock auto would roast the tires from a stop Are you kidding? ALL 3.4's regardless of transmission type can spin the tires.

Prospeeder Posted January 10, 2006 Report Share Posted January 10, 2006 I have new found beleif, if a 1990 Maxima 3.0 DOHC can have smoke come off the tires just by flooring it from a stop with 160 horses, in an auto also, then im sure a 3.4 dohc can Quote Link to comment Share on other sites More sharing options...

Wait, but I thought before he said they had nothing but high end power? lol Quote Link to comment Share on other sites More sharing options...
birdman Posted January 10, 2006 Author Report Share Posted January 10, 2006 workin on this job thing but ill have an update very soon. Quote Link to comment Share on other sites More sharing options...
Pabz Posted January 10, 2006 Report Share Posted January 10, 2006 Question, Could a restricted exhaust (ie, clogged cat) reduce low end power? My experience, Gutting cat and putting back stock air box as well as the engine side poly inserts for the dog bones helped free up some low end power but reduced high end where it counts!

slick Posted January 10, 2006 Report Share Posted January 10, 2006 Too bad we dont have any dyno graphs of a stock 3.1 to compare to a stock 3.4. You would see that the 3.4 has more low end power than the 3.1 does. The weight of the 3.4 over the front tires generally will keep it from spinning its tires, unless the tires are shitty, or you do have mods done. Me personally, I have problems with wheel hop Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted January 10, 2006 Report Share Posted January 10, 2006 As much as i detest this engine, I've lit up the tires a few times with my car. And its bone stock. Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted January 10, 2006 Report Share Posted January 10, 2006 All the 3.4s I've drove (mostly 95+ Montes that have been sitting at dealerships, and all of them were automatic) basically felt like they had the same amount of bottem end as a 3100 engine. Of course, after 3k or whatever it just keeps on going... Quote Link to comment Share on other sites More sharing options...
