Hey guys, I’m having some problems figuring this out. My 96 Accord 2.2L 4 Cyl. idles around 1200 RPM upon start up, after letting it get to normal temp it’ll drop to around 650-750 RPM. But when I put into reverse or drive (D4) it drops to about 500. And when it sits in either gear for a minute or 2 the engine sounds like its idle is bouncing but the tachometer stays between the 600 and 550 and will drop over time. I’ve tried resetting the ECU but that didn’t do much. I didn’t have this problem before checking my head gasket. Any help would be greatly appreciated, its the only vehicle for my family. Thank you – Chris

if you checked the head gasket by removing the head, you lost coolant. I would bleed the cooling system for air.
I did bleed the system best I could, I may have done it wrong though, cause when I turn the car off, coolant and air come out of the bleeder valve. Would that mean I need a new bleeder valve and that’s letting air into the engine ? I didn’t know there was a bleeder valve before taking the head off. Thanks
If coolant and air are coming out on its own. Then that would explain the loss of coolant which now will take in air.
Replace the bleeder and top off the coolant. Re bleed the system.
