OK guys it finally miss fire again.
I got the same code as always P0305, miss fire on cylinder #5.
This is what is did so far prior to miss fire:
- Checked plug #5 and gap and it was clean with a perfect gap.
- Switch coil packs
This is what I am going to do next:
- Check the spark plug wire for plug #5.
- Check fuel injector #5
Let me know your opinions.
BTW the miss fire only happens climbing a steep hill on the interstate when the RPM starts getting low and before it downshifts, also the engine light starts flashing during the miss fire.
While I am writing this it seems to me it could be the injectors. If it is the injectors should I get DIY fuel injector cleaner that connect to the injector rail .
Advance thanks for any suggestions!
George
