ok i already searched this and tried the fixes(execpt for tps adjustment but i do not believe that it is the tps right now)
ok about two days ago my car started being bouncy during the warmup around 1500 rpms and it also does it after the car has warmed up but only in the 1400 to 2500 rpm range. the car runs fine in any other rpm range and even idles fine below 1300 rpms. i have no hesitation at higher revs at all so....... i searched and it said that it could be the BAC/high idle valve. well i cleaned and checked that and it made no difference in the way the car runs. also, in first gear, if the rpms drop below 1300 and i try to take back off i get alot of shuddering.

anyone have any idea what it could be? could it be the tps after all?? any suggestions at all would be nice.

 

I chased a similar problem like this for a year on my 90. Turned out the whole time the BOV was leaking. Id suggest checking for vacuum leaks.

 

i guess i should have said this before.... but i have an 88 N/A if that helps at all.

i don't think that i have to worry about a BOV leak but thanks for the suggestion about vacuum leaks. as soon as it stops raining here ill have to do some tracing of lines to check for cracks or disconnections. ill update tomorrow if that was it or not.

if anyone else has any opinions as well ill be happy to hear them. can't hurt to have more than one thing to try to fix this.
