AOA.
My honda has a rpm problem now after i fixed the IAC valve.
I changed the ECU from P6F to P2J as my engine is D15B.
The Old ECU had IAC valve problem.
But now After changing the ECU, my car's rpms at idle are bouncing between 1000 and 2000 continuously.
there is no problem on CNG, but on petrol, the rpms fluctuate.
Anybody has any experience with this kind of problem,?
