Strange Idle
 

i just got a 91 n/a and i have some funky idling problems. if the idle is set at stock specs (1000 rpms or so) it will start to bog out and eventually die whenever im not running it. right now i have the accelerator turned up so that it doesnt happen but i dont want to be cruisin at 2500 rpms. my friend said that it might be one of the idle sensors and ive read that it could be the vacum hoses, the TPS or the BAC. first of i dont know wat either of those 2 r, all i know is i want to take care of this car as much as possible. does anyone know which sensor it could be?

Check your intake piping for cracks or openings.If t's one of yor sensors it's most likely your bac.The tps would usually would make you engine run erratic throughout all engine speeds.
