I'm sorry you are having problems with your vehicle. I will try to help.I'm a full time mechanic and have been a mechanic for over 20 yrs and I work part-time here on JustAnswer to help you and others repair their own vehicles, and I get credited by your ratings.. So before leaving the site make sure and leave me a rating. You can still reply to me as many times as neeed, even after the rating.. I will need for you to be my hands and eyes since I'm not there.I order to help further, I need a little more information.
Has it done this ever since you redid the head? Or ran normal then started sometime later? And have you checked for injector pulse?Thanks
Customer: replied 1 year ago.
it started after skimming. can it be air escaping from the head? does the block need skimming too? BUT THE COMPRESSION IS OK IN BOTH CYLINDERS. INJECTOR PULSE IS OK
Expert:  Master Auto Tech. replied 1 year ago.
If spark is ok, compression is ok, and injector pulse is good but started after the repair then I'd double and triple check that the electrical connectors are hooked up correctly and to correct cyl on the coils and injectors. Is the cel and if so what codes are there? Also do a leak down test. That will tell you if there are any really leaks. As for the block, I have never had to skim a block, ever. So unlikely there.
Let me know what you find with the electrical connectors and cel.Thanks
