    Erratic Engine Revs

    Running rich could be all kinds of things. The car is dumping fuel in to balance out something wrong. A good shop can still pull data from the ecm. That’s really the only way if you’re not going to wrench it yourself. Could be a bad O2 sensor., vac line leak, FPR is shot, even a bad temp sensor can make the ecm run the car rich.

    Tgp exhaust leak under hood and runs rich

    Thanks for getting back to me. I found a bad injector. It wouldn’t start. Had a na 3.1 back in the day that died while driving and ended up being a shorted injector. Also got the knock sensor out. Broke the clip though. Squeezed to hard I guess. When I get it back together I’ll post if it runs better. I think the exhaust leak is all crossover! If it at least runs better I will work on pulling that out next to have an exhaust shop fix it hopefully. If anyone still has a step by step on the remove and install of the crossover please post it if you can. All links are dead looking for this stuff these days. Also does anyone have an old chip they would sell for the ecm? Those links and people who did them are gone also. Sure would like to get some more hp if I get her running good.

    Starting the hunt for a 91 Grand Prix GTP

    Agreeing here with what everyone else is saying. Here in the States, it seems the Z34/5 speed cars are the most common. If I were you, and if you're really wanting a 5 speed car, I buy a 5 speed GTP, PLUS...a Z34/5 speed car for just parts. You could then scavenge what you needed from it to get the GTP reliable, (if it's not already), or have a back up parts car for when the time is needed. I post any rare cars that come up for sale here so please keep an eye out for that information. I also post junkyard cars that people can scavenge from in order to keep our cars alive and road worthy. I also do it for historical reference as well.

    Starting the hunt for a 91 Grand Prix GTP

    Hey Brad. I saw both of those GTPs on Facebook marketplace. I live in Kelowna so check often (looking for parts always). I’d pull the trigger on the blue GTP just because I love that colour on a GTP. I checked just now though and can’t find it so maybe it is sold. The white GTP is back up for 4500 I’ve never seen it around Kelowna so not sure if it’s like mine and just sits most of the time. It has the B4U lower valance intact so that’s a huge plus. You could probably get the seller to move on the price. GTPs of this era hardly ever come up in BC so you should pounce. You might not ever see another in that shape again around here. As for 5speeds. I’ve only ever come across 3 of them in my life. And 2 of those 3 transmissions are on my bench and took 15 years to score way back. I have all the parts for a swap and slowly working towards an engine rebuild and install. Forget the 5 speed it’s a true unicorn now, was 20 years ago. Even if you found a complete junk parts car all your efforts are best placed to just get an auto to restore over time and enjoy. I would look carefully at the trailing arm mounts for rust, if it’s solid there go for either car. If you get the white one painting the hood louvers white should be your first order of business. just heat the screws up before you take ‘em out.

    Thanks again, we`re going to have to get all these cars together at some point so you can check it out. Its been years since a meet up happened. Shes going to the show, May 17-19. I`m going to try to find some seat covers that fit good and might give that dash cover a shot on RA to hide the crack. The paint might not be in the best of shape with the orange peel and fading wheel arches and I`m not the best at talking with strangers but it should be a good time.

    Tgp exhaust leak under hood and runs rich

    Welcome to the forum! First things first, get that crossover replaced, that will cause all kinds of running issues with it. Exhaust leaks wreck how these cars run. A point of advise, probably not relevant at the moment but I seem to remember decreasing the spark plug gap from whatever the factory recommends to help with some other running issues. There is only one person i'm aware of who repairs those at this point. Forum member GOT2BGM aka Matt Shantz he's not on the forum much these days I'm sure he's active on the various facebook w body groups but regardless i'll shoot him a message to drop by the forum.

    Swapping out rod bearings without taking engine out

    Doing that "in the chassis" would never happen in MY driveway. That engine would come OUT, so I didn't have to work on my back like a prostitute for the whole job. Flip the engine over on an engine stand, rather than flipping the worker over on the concrete. Likely get a better job done with the main seal, pan gaskets, etc. High mileage? Timing set, rings, head gaskets and valve job. MAYBE bore + pistons, crank grind, block decking...

    It had to be saved, it was going to the Jawas otherwise. All Jiggity57`s fault for posting it. I got into a bit of a race the other day when I probably shouldnt have. I made a right turn and immediately found a speeding BMW attempting to swerve around me from a sharp corner in the right lane. I laid into the pedal a bit, chirped the tires and heard an awesome turbo wastegate PAHHTISHHHHH and left the kraut cart far into the rearview mirror. Scared the hell out of me and blew the lower hose off the turbo in the process. I love this freakin` car! Decades after WW2 and we can still put the Messerschmitt`s in their place, just not in a P51 Mustangs.

    Here are some 5 speed stats for you. I think finding the cleanest car body wise you can auto or 5 speed would be your best bet. even if it needs mechanical work, that can be done overtime.

    Starting the hunt for a 91 Grand Prix GTP

    Welcome! Great backstory, I think it captures why many of us still love these cars. So you covered a lot of ground I'll try and hit on some points, not to scare you off but to inform. If you encounter a 1991 with ABS, don't walk, RUN. That was the last year the old PowerMasterIII braking system was offered in these cars. It was troublesome 35 years ago and in my opinion totally unsafe to use today, and its a massive headache to get rid of. Just spend some time reading here and you'll see. 92/93 had a far more reliable however underwhelming performance of the Teves IV ABS System. the "high oil pressure" is likely nothing more then a bad sending unit, when they start to fail they will read all over the place, $20 for a new one no big deal A 1992 will have the highest possibility of being a manual, not sure on production numbers but 1992 was the most common year for manuals, again still very uncommon but highest chance. As far as automatic vs manual, I've done both flavours of the 3.4 DOHC, the 5 speed is more fun but its truly a hateful gearbox to live with on a daily basis. I'm good with it for a few days before I get sick of it, your mileage may vary. There is also the reoccurring problem of these cars in the 5 speed manual, no parts! you can get axle seals, clutch sets, sometimes clutch hydraulics and not much more. Shift cables are another issue they don't break often, and you can repair the main shift cable when the rubber bushings fail. But the cables themselves, they are unobtainable now. And lastly Timing belt components are getting harder to come across, specifically the timing belt tensioner actuator, its been discontinued by GM and you're basically scrounging old stock or used ones at this point. Literally no idea what I'll do next time I need one. Probably have to get creative. The video of that 91' you posted sounds in a pretty sorry state, could be something simple. Can't really tell from the video. Of the 2 you are looking at the white one with cloth looks better taken care of. That said, If you do want one try and hold out for a nice one, at least around me these cars are just gone from junkyards so replacing broken pieces could be a challenge.
