i got the cylinder 1-2 misfire... car runns perfect still until the cel comes on .. then leans right out, done every test i can think of .... here is what i have done so far..

new maf/comp test/new coils/new plugs/vacuum/boost test/tested injectors individually.... running a dynamic comp test (while car is running test compression) i guess if im off by 2psi my valves are bent? anything else i should be looking at?

 

i had a skip on 3 on cold start ups..turned out to be really dirty intake valves causing them to stick

 

did u regap the new plugs?

 

yup - we think its phantom cel / shitty ecm
