Engine Performance problem
2003 Kia Spectra 4 cyl Two Wheel Drive Automatic 60000 miles
2003 Kia Spectra-
Randomly misfire on cylinder #1 verified by pulling p0301 as well as p0300 p0302. Spark plug #1 is wet, and is firing. Swapped coil packs to verify. Problem remains in #1. Swapped injector 1 and 3 problem remained in cylinder #1. Compression test verified all cylinders have 150 psi. Cylinder leak down no obvious indications of a problem. When I start it for the first time or after it sits for 5 ten minutes it will run just fine it’s when I put a load on the car is when it starts to misfire and doesn’t recover until it sits for a while. Lost on what to do next.
have the same problem?
