whats up guys, i have a problem any help is appreciated, 91 integra first start up and idles good, but when i give it gas its revs up but when let of gas its dies, also when on the throttle at a steady part like (40% open holding) car revs up and drops down without letting go of the throttle. no cels and change dthe tps twice and map sensor twice,, even converted to 0bd1 to run a s300 hundred and the same thing happens thanks for reading this

btw i have crower 404 can this cause the problem?

is the car tuned? if not: do it.

mine was doing the same thing awhile back i bleed the coolant system and it instantly ran better. try that with any luck it'll be an easy fix. your engine should have a bleeder valve near the thermostat housing. theres a video on youtube, cant remember the name but shows how to do it in detail. good luck hope this helps. try "bleeding coolant system" on youtube.
