Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
were the wiring connectors checked?
were the injectors checked or at least swapped?
Customer: replied 1 year ago.
Coil connectors looked good, I have not done anything with injectors. I'm thinking bad injector would stay bad. When I performed compression test, put everything back together, car runs like brand new. Smooth, no stumbles, hesitation, plenty of power. Never has mpg effected.

Hello,
when exactly (in which conditions) do you get the p0302?
And injectors like coils are affected by temperatures, so sometimes an injector would be good at cold and bad when warmed.
