hi just did an h22 swap on my accord and it wont idle at all and i have to advance the timing all the way for it to starts and rev and its running really rich
I did a vacuum test and it says i have slow timing but i cant advance the timing anymore need help please

 

Have you checked that the throttle body stop is in the right spot and closes properly/doesn't stick/bind?

Also check the idle air valve, it might need to be cleaned.

But advancing timing like that normally means a vacuum leak

Here's a simple way to tell

Take a can of brake cleaner and spray it at every mounting flange/gasket area, any where along the intake tract where there could be a leak. If you have one the rpm will climb as the motor burns the solvents

Is this motor na or boosted?

Stock ecu?
Bigger injectors?

We need a detailed list of what's been done... modifications, etc to be able to help you properly

 

im running turbo camshaft low cp piston the ecu i a p28 chipped stock injectors its starts and rev fine but as soon as i let go of the throttle it will stall and thank for the reply

 

and how do i do the vacuum leak test since it doesnt idle i get a friend to hold the rev while i do it?

 

fixed the prob the timing wa off by one teeth now she is idle but a bit high im going to play with the idle screw to fix it

 

That was going to be my guess, glad you found it!

 

thanks the idling screw didnt help at all so i retarded the ignition timing and idle went normal :D
