ok heres my problem,about 6 months ago my idle controll valve crapped out on me.i replaced it with a used one from a 92 integra,my idle was jumping drastically when it went out that time, the used valve fixed my problem,solid all was good.now when i start my car every thing is fine, i drive for about 1-5 min and only when i get to a complete stop"light,stop sign,what ever"my idle instantly dropns to 500 rpm then jumps to 1.5k to 2k.then back down to 500.it get's right to the point were my motor dies then jumps up again.i checked for vacume leaks and founf nothing,i replaced the idle control valve one more time,this time the only thing available was from a 94 integra,"took some modifing but it works.it didnt fix the problem.i reset my ecu after i changed it to see if it would make any difference and again nothing,its still doing it.i dont have a cel light in my cluster because for what ever reason who ever did te swap took it out.could it be a bad tps sensor? i took it down to my buddies shop and they fiddled with it but nothing.any ways,the motor in the car is a first gen b16 in a 91 hatchback.any input is greatly appreceated,pat.
