RPM arrow trouble

395

Asked by joy1025 Oct 22, 2014 at 11:51 AM about the 2004 Toyota Corolla LE

Question type: Maintenance & Repair

As I turn on my Toyota corolla 2004 LE, the RPM arrow goes to 2 and jumps up and down between 2 and a bit higher, while the car is in park. Once I put in any other gear it goes down to close to zero.  What could be causing this? My check engine light came on just this morning but this has been happening for a while.

Likely IAC valve, Idle Air Control, but that's a guess. On OBD scan will eliminate a lot of guesswork/ MAF MAP 02 sensor lots of things could be sending the wrong signal to ECU and it doesn't know what to do. or vacuum leak
