hello everyone a friend of mine is having some trouble....

95 jdm h22 swap into a 94 del sol...it starts sometimes but stumbles....if we get it to start it idles fine until it get warm and starts to miss....if we gas it, it'll rev fine till about 4k then it misses....thinking bad coil or something to do with timing....

has spark...
compression 190psi across all 4 cylinders
no ecu codes....
new ecu....
checked map....
havnt checked iacv....

any other suggstions???? cars been running fine for 2 years...all of a sudden this happens...any ideas would be helpful...TIA

 

yea my car is doing the same thing...i dont know what it is i think its the spark plugs maybe but idk! and it sounds like a harly.....sorry i cant help you out much on that one but if i do find something out ill let you know.

 

Check your plugs. Also are you getting fuel? Recheck for spark as well. I have had multiple distributor problems with my h22
