Bought my car last july and has run great since then til now. The clutch went out, so I installed a SPEC 3 clutch with a lightened flywheel. Since the install, the car will crank fine, and even idle normal, but in light excelleration you can feel it buck slightly, and its like its in and out as far as power, but still driveable. Also when driving, and depressing the clutch when comming to an intersection or stop, the RPMs drop to like 400 or 500 RPMs or it will stick at like 12 or 1500 for a couple of seconds, and even cuts off a lot also. There is no check engine light on, and I pulled the fuses and let it sit with the key on for 5 minutes, and all, and that didnt help. Also something weird is sometimes the gas gauge will drop past empty every once in a while at random when the car starts acting up. Anyone had this problem after a clutch install, or could it just be coincidence that something else went out randomly? Any help would be great.
Thanks

Broken or pinched sensor wire/ground when reattatching tranny happens more often than you would think.

A few things:

Be sure you got your 02s hooked back up correctly and the wires are clear.

Did you handle the 02s carefully when you removed the exhaust?

Do you have any exhaust leaks?

Check the vacuum lines at the back of the intake.

How many miles since you installed the cltuch?

Im goin to put the car on the lift to make sure if any ground wires were left loose, There were no wires pinched and the scan tool showed all O2 sensors working fine. Someone said that the crank sensor might have been unhooked wlhile removing the starter and forgot to get hooked back up or it could be loose. Could that have something to do with it?

No. If you had done that your car would not have started, period.

I couldnt find any loose grounds, everything was hooked up, and no pinched wires. Couldnt fand any vaccuum lines loose either. I have no idea. Also its like it will only do it past a certain mph or rpm. Sitting in the parking lot and reving, or driving through the lot it wil not do it. Its only in like 4th or higher going down the road when you press the clutch pedal. If it doesnt cut off, it goes from like 400 or 500 to like 1000 to 1200 back and forth also. Thanks for the help so far.

Which one of your cars are talkin' about.
I may have clue, but you need to provide more details on the car in question please.

My SPEC 3 seems to be doing fine under quite a bit of power...

i have a idea man it happened to one of my friends once. kind of a long shot, but when he droped the rear of the trans down to get to the top trans bolts it pulled the smooth bellows of the throtel body just a little bit so air was getting sucked in without going through the MAF! it was doing the exact same thing as what ur saying. like i said its a long shot but easy to check.

I recently had the same issues. Turned out to be one of my 02 extension plugs got melted by the LT's. Replaced that side with the infamous Bosch 13111.. Car runs great now.
