OKay so my 1998 Honda 4 cylinder automatic Accord LX starts and runs just fine but it wont idle at low rpms without dying UNLESS ive been driving it for 30 minutes or more when its warmed up then it idles just fine. When I start it, I HAVE to keep the Rpms up above 1200 to keep it from dying. If it goes below that, the engine idle becomes rough and just dies. I have to keep it above 1200 rpms and then quicly shift into Drive to keep it from dying. However, once I drive it around for a bit, the idle is just fine. It sounds like its trying to get suction or intake air and its failing. When I press the gas pedal at low rpms, I can hear it(a hollow noise) in my exhaust pipe. When the idle gets low, the engine chugs and feels like a bouncing underneath my car(like a rough idle then quits). Its not my fuel intake or pump cause I can hear it turn on and plus, its unserviceable(i checked). Spark plugs are fine. I got a diagnostics check and it says my MAP Sensor says my engine pressure input is running too high. So I figured its my IAC since the highest engine pressure is at idling speed? HELP Thanks alot :)
have the same problem?
