Ok...I will give you some background on this then thank everyone for their help and information on H-T.

Got a JDM H22 for $300 from some old guy who bought the wrong engine in Dover DE. I love this place...its like stupid people live to please me here.

My F22A blew up at 214,000 miles on Route 50 in Washington DC so this was well needed.

After the swap I had the notorious surging idle issue. I'll go through what I did exactly.

I did what it said in the book to adjust the idle by unpluggin the EAVC then adjusting the idle at operating temperature. This did not work.

I took off the EAVC and cleaned it but this did not work also. I took off the Fast-Idle Control and cleaned that and adjusted the white thing inside of it. This made it better but came back after warming up.

I had an extra complete H22 intake manifold laying around so I swapped the EAVC and the Fast-Idle. This did not work either.

Come to find out a little later that the guy that sold me the intake manifold that currently was on the motor put an EGR block-off plate on. I took that off...cleaned the EGR...started it up...and re-did the idle set procedure.

YAY IT WORKED....it worked even better after I drained out the old gas that I had in there. Unleaded. I put Supreme in with some Octane boost. Now its runs perfect.

Of course all the things in this post should be a step at fixing anyone's idle problem...but I believe it was the EGR that was the problem. A blockoff plate also makes the idle at little high I believe.

Anyway...I'm not looking for a response just wanted to say thanks!

 

good info, those damn idle problems can be such a bitch

 

damn, maybe it is my egr. too bad i cant hook it up i might have to deal with it until i can get a chipped p28

 

Good to hear things are working out, Anthony.

Did you do anything regarding paint yet? What about that planned black interior?
