hey yeah my friend has a 92 integra gs that does the same thing.. and my neibors 91 accord does it and i know alot of other misc hondas that do it... its not a big problem at all its just something simple like a vaccum hose or sensor is bad.... i cant remember exactly but they mostly do it if you put a custom intake on them... usually they dont have a plug for the stock vaccum hoses... ill find out and get back to you with more information but for now check the vaccm hoses on the intake and make sure none leak... ill try to get back soon with more info fo you but like i said nothing to really worry about just kinda anoying....

Yeah my 94 integra LS does the same thing but when its idleing it goes up and down but when starting it goes up to 3000rpm when cold it goes up to 2000rpm its a bad sensor. The engine is thinking its cold so it injects more fuel in and then cools down thats what the problem is.

I have a B20B in my GS 93 integra and my idleing goes straight to 3000 rpm and sometimes it goes up and down between 1000 and 3000 randomly. Can it be anything other then the sensor like maybe the ECU because my ECU is from the GS Integra.
Im wondering if its a big problem and does anybody know how much the sensor is. Thanks.

its your TPS (Throttle Position Sensor), u cant buy these from any part stores as they are dealer only parts and from the dealer they cost $500-$700, but u can buy online anywhere from $30-$80, or u can just get off basically any honda/acura thats 1992+ and it will work on your car

My 91 Integra bounces randomly around 500rpm to 1500rpm its a pain... lol
