The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.

Deffinately clean the throttle body first.. "The butterfly area" use brake cleaner spray or carb cleaner.. mayby a scotch brite pad or green pad all around the butterfly.. If it doesn't fix it then find where your vacumm leak is at..

SOURCE: Stalls at stop when at peak temp

My problem wasn't the O2 sensor. Finally threw a code...106 then 107 and 108...Map Sensor and circuit. Checked the wires and found no issue. Then tried to clean the nipple where the hose from the MAP sensor went into the exhaust below the throttle body and I couldn't get a pipe cleaner in there so I sprayed some wal-mart break cleaner in it and continued to attempt a breakthrough and sure enough it cleaned out and now no issue at all. Yay me!!!

SOURCE: Runs Ok...engine warmed up...come to red light or

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

SOURCE: My AC blows hot air at stop lights. It works great

Have you radiator clutch fan check out, sounds like its bad, air blows through radiator and a/c condenser while driving and no air blows through at stops, will cause a/c pressure to go up and not cool.

I have a 1994 buick skylark with 2.3 and a/t it runs and drives great except when slowing from high speeds it dies when approaching a stop. it jerks like transmission isn't shifting. when u restart it,...


Check for vacuum leaks on all hoses underhood. Make sure all intake componets are intact and they are tight.

Is the check engine light on? If so, get to an auto parts store, they should pull the codes for free.

Sounds almost like a bad throttle position sensor. The computer uses the TPS to help know when to shift on this car if I remember right, and if the TPS is bad, it can cause that jerking. Along with the car dying when slowing down after driving. But check everything else out first. Including electrical connections.

Idle air control valve is usually the problem when you have no drivability issues and no codes other than an idle issue., Clean the throttle body. this may help but if it doesnt you will need to swap the IAC out.
