Hey there, recently rebuilt cylinder head in my escort 1.4CVH EFi engine. Having problems with eratic idling. This is my first engine rebuild and am completly stumped. Had it off 3 times now trying to get it sorted but everytime it runs the same. When it runs idle its calm then gives a burst of gas every second or so as if the things about to stall. Ne help would be great.

Cheers

 

idle control valve

 

Air leak, running lean and anti stall working ok!!

air leak from the inlet manifold or something? I was worried that there was a leak from the head gasket so it was getting poor compression? Would that cause it?

Cheers again!

 

head gasket it would leak and be very shit and youd get no heater

 

I think you're wasting your time keep taking the head off, the problem is more than likely a lot simpler than that

As said look for air leaks and also give your ISCV a clean, they go sitcky and dont work properly
