I have a Civic ESi '94. Idle is at 700 around, which should be normal. If I accelerate a little, the idle goes up to 1500, than down to maybe 300 and back to 1500 and stays there. That "going down" to 300 or below let the engine sometimes shut down. What can that be? Its like the engine dont get enough gas for a very short time. The needle is not moving or something. Everything is normal once after a second.
Idle problem
- Thread starter softtouch
- Start date
Do you have an intake in your car if it is a cheap one i had the same problem the rubber surround is letting dirt into your car and it is clogging the mass airflow sensor I had to take it to a mechanic to get it fixed hope that helps.
have the same prob too
i think it just need more gas or sumthin

Its not the intake, not the gas filter, not the spark plugs, not the PCV... all checked already and all is fine.
I noticed that if the A/C is on, it is even more worse. Cant start accelerating normal. The rpm goes, for example, up to 1500, drop down to 200 (sometime even the engine shut down) and goes up to normal after that. If the aircon is off, it goes up to 1500, down to 900 and back to 1500... I have no idea what that can be. I even was at honda service center and they said, thats normal (maybe they are not normal!)...

umm no, this would not cause the car to bounce the idle, but hey if you can prove me wrong go ahead.Catalyc converter or muffler could be dirty/clogged
