My 95 corsica shaking & wanting to stall especially when stopping or decelleration. Got car home & it would not start w/out having gas to floor, it starts but runs really rough as if only on 2 cylinders. I replaced everything I could think of to fix it, (to no-avail). First I got new plugs, wires & ing. Coil packs and replaced all. Then I removed fuel tank and replaced fuel pump & filter(Needed it also) Then I thought the Cat. Conv. Could be plugged so I bypassed it & (still rough). I have tried everything I can think of. I have already purchased too much and still not fixed. I must get it figured out! I have done some research and will try to disconnect TCC and see if that works. Is there another censor or something else mal-functioning to cause this?(If so pls explain location) Please take time to read this I really need the help thx.

Firstthing to do is take it to an autoparts store and get the engine codes scanned to see if a sensor is causing the problem. Then clean the throttle plate with choke cleaner and make sure your duct work is not cracked or broken between the air cleaner and throttle plate. Then check the car for vacuum leaks, use a vacuum guage if you have one. If not take this to a pro and he can diagnose it and save you a ton of money like yo've already spent and still haven't fixed the problem.
