I have a 91 Integra LS and for some reason ever since I replaced the thermostat and did a tune up, (plugs, filters, fluids, cap, rotor), my idle does not stay in one place. It tends to idle high and if I put my foot under the gas pedal and lightly pull the pedal out just a little bit it drops the idle down. I adjusted the idle because when I got the car the idle was so low that when it was in gear the whole car shuddered. I adjusted it and now it can't make up it's mind if it wants to idle high or low. Somethimes it even jumps high, low, high, low, etc. Any idea's as to how to fix this problem? Please let me know. Also, at idle speed the exhaust sounds like it is sputtering. I think I got a bad car. Any idea's??
