Hooked it up again and the same codes were present: P 300, 301, 302 and 303.
It was stored for two years with little fuel in the tank. Any possible problem here that will affect bank 1 cylinders only? |
Does your scanner show freeze frame data?
That is data showing the conditions or some of the conditions when the codes were set.
If I remember correctly most all OBDII scanners that show freeze frame data show data for the last code only.
But Since all your codes are related there may be a clue to whats triggering them in the freeze frame data.
Still need to look at the coils, plugs and wiring harness though.
