Hello everyone! I just bought a 93 civic ex that already has a greddy catback exhaust, hedman header, Zex racing camshaft, aem cai, and a coolant bypass mod. My question is, sometimes after driving, my car idles at about 800 rpm, and then jumps to about 1200 rpm. It continues to do this constantly at idle. What could be causing this? Is it the coolant bypass mod? Also, the engine is noisy under acceleration, but isn't when in neutral and I'm revving it. Is this the camshaft causing this noise? Thanks for any help everyone!

I forgot to mention that it also has a ported throttle body. The noise it makes under acceleration is kind of a grinding sound. Thanks!

prolly the cam doing it. yur engine can rev high now most likely. internal mods r hell on engines.

is your a/c on when the idle does that? i know that when mine's idling with the a/c it drops to like 800 er so and pops back up to 1000 sometimes, but stays pretty much at 1000 when a/c is off. i think it's normal, but whoever messed with the car b4, musta turned the idle up justa tad.

get it looked at. :thumbs up:

No, the a/c compressor isn't running. It also doesn't do it always. Seems to do it more when I've been driving for a little while and come to a red light. It jumps from about 800rpm to about 1200 rpm give or take a little bit. It does this perfectly in time, not as if it isn't running right, but it still seems kind of annoying. Sometimes it doesn't do it at all. What do you think?
