Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
hello my name is ***** ***** is the phone call request that you as ask for as soon as you accept i will give you a call
not a problem no you still need help
yes can you send what information you are getting
can you check compression on cylinder 1
compression shouldnt drop below 140
then i would agree you have good compression
run a fuel pressure to test you have already checked the spark plugs correct
Your next step here as it looks like compression is good is to have cylinder 1 fuel injector tested.I have seen the injector fail to atomize properly to where it needs cleaned or replaced to correct this fault here.Instead of testing it you can try and swap it with another injector on the fuel injector rail and see if the misfire moves to the cylinder you swapped it with.If it does then this is the fuel injector that needs replaced.If you want the test procedure let me know but this will require a fuel pressure test gauge and a scan tool that can pulse the injector.
