The tranny mount took the shop little over an hour to do with 2 people working on it. The modulator valve would be easy to do, providing it isn't -20 outside! LOL. Alternator? Piece of cake!

I've had that thing in and out so many times now it isn't funny...mainly to gain access to the rear plugs. Only recently did I learn you can bring the idler pulley up with a ratchet! LOL

Those guys must have been in each other's way to take an hour for a transaxle mount change on one of these cars. :laugh:

Why's that? You think it should have been easier or harder? The shop book says 3 hours....

Easier. If you have everything you need handy, you can swap them out quicker than that. Book time doesn't necessarily reflect the actual time it takes to do a job. Some jobs, you'll finish much quicker than book time, others you'll break even, and then there are some that take longer than listed. I prefer changing trans mounts to engine mounts on these 3.1's any day, there's more room to access the trans mount than the lower engine mount. :icon_mrgreen: The lower engine mounts aren't that bad though...having an offset ratcheting wrench comes in handy for those. ;)

All I can say is Wow. I thought my TGP had problems but after hearing you problems I don't feel as bad. I am glad you got everything worked out on that car. I am new to this site but my screename on wbodys is shadow.

Hey! My screen name on W-Body is Krenzy lol.

Hey guys. Well, my car in the last couple days has developed a couple things that I believe warrant resurrection of this thread lol.

1) Idle is terrible. It's never been 100% perfect, but now it's crappy.
2) When I start the car, I need to give it a few tried to get it to fire. When it does fire, it almost sputters out, but catches itself.
3) Twice now when I've first started it, the idle surges, I think is the word. It bounces RPM's between 1400-1800ish, then after a few bounces, it steadies out...but the idle's still bad.
4) Car has lost power, I believe. It's still quick, in 2-4 gears, off the line it's slow. Might be related to the chip, or new tranny, or to the idle problem, I dunno. I'm not terrified because I still get great mileage on the highway.
5) Kinda seem like I hit fuel cut or something...like from a dead stop I'll give her a hard pedal, and it spools up great, whines nicely, but towards the end of the gear you can hear the whine sputter and flux.

NOW: I do have a small exhaust leak, and have since I changed the crossover, but that's because i cannot line up the crossover. I just don't have the time to remove it and fix it. Not too worried about it, since it's idled alot better and still had the leak.

Before I even think of selling her, I want to fix these problems, so any help is appreciated.

Nearly everything has been replaced within the last two years, but it's entirely possible something went bad already. I have my suspicions, but I'll wait until I hear what everyone else thinks.

SO PLEASE HELP ME!

Anyone got anything?

sounds like a vac leak could be causing some of those symptoms.........I would also get that xover sealed up because that is not helping you either.  Is your IAC dirty or stuck or something?  That could cause the idle surging.......  I usually start with the stuff that is wrong and work my way to the problem I'm having......sounds like you have a few gremlins to work out before you and pinpoint any particular problem.....

See I thought I might have a vac leak too, but I can't find one. I even checked under the plenum.

I had my IAC off the car a month or two ago, and cleaned it with carb cleaner, so I don't believe it's stuck, though I honestly don't know how to check if it's stuck.

Crossover I'd LOVE to fix, but time and location generally interfere...so while I know that is a problem, I know that's not the main cause to these problems, since it's run fine before with the crossover not being mounted correctly.

I had a funky vac leak one time, around a fuel injector!  the o ring was not sealing well and I was getting unmetered air being sucked in past the injector.  Just a reminder that vac leaks can be anywhere....even things like your throttle body gasket, egr gasket, egr valve being bad........make sure the egr is working properly matter of fact.  I had a buddy with a stuck open egr one time and caused him hell for a long time.....

My EGR is deleted, as my chip doesn't require it. And the blockoff plate is secure. Thanks for pointing out other options for a vac leak. I should note that when I opened the hood the other day, it smelled strongly of gas. And just now, when I got home from the post office, I got out of the car, and could smell a strong gas smell just by exiting the car, as soon as the door opened.

Fuel regulator? See if you have raw gas in the vac lines at the regulator. Bad o2? I seen them fail and never set a code.. Faulty injectors? I'm sure you have replaced those but keep it in mind.. Vac leak? Get a spray bottle of water and start spraying trying to isolate the source...     :icon_mrgreen:

Yeah O2 is about four months old, AC/Delco, but it's possible.

Where should I spray water?

I'll check the FPR here before work.

Spray around all vac lines, throttle body, injectors if possible, upper to lower manifold and lower manifold to heads. If you have a leak somewhere it will suck the water in and bog the engine..
