Hi, I'm Ron and I will be helping you today.Stand by for a moment while I prepare your answer.
Check fuel injectors for proper operation with an injector tester and make sure they are getting powered by the computer.
Check engine compression with a gauge.
These are the only items left that can cause misfires.
You need to have the proper tools.Most parts stores will loan them to you for a deposit. Compression should be about 170 PSI.
Thanks again and please remember to rate me 5 stars and keep this link in case you need me later on.
You check the injectors with a machine, you don't pull them out
No, you need an actual fuel pressure gauge and the injector tester to attach to it too and you need to know how it works as well. Most parts stores will loan these to you, give you instructions and readings to follow for just a deposit. Please rate me now and we can then continue out conversation if you still need help later on.
If you are satisfied with my answer, I would greatly appreciate a 5star rating now and I will still assist you after you have rated metoo if another question pops up. I don’t get credit for helping youuntil you rate me.Thanks again, Ron
