2003 Liberty P0300, the dreaded multiple misfires (with a twist!)
Ok gang, I got a weird one on a 2003 Jeep Liberty 3.7 with 160k miles. CEL on, multiple cylinder misfire code (P0300) only, no stuttering, no loss of power, no detonation, no unusual engine noise. I have replaced all spark plugs, all coil packs, PCV valve, and the crank sensor. It's still throwing the CEL and P0300.
The weird thing is the CEL and code appear at 3/4 of a tank and disappear at 1/4 of a tank. So above 3/4 and below 1/4 gas there is no CEL or error code. It has done this with regularity the last 20 tanks or more.
In at a loss, anyone had this happen before, or have any ideas?
