Guys,
I have a 200JK with a QR20DE engine. It has approx 169k KMS on the engine and I am getting a very strange issue. The car runs perfectly except for an intermittent rough idling/ Missing / bucking issue. It happens on cold start and you can feel the miss while driving normally as well. It feels as though a cylinder is not working.
Info:
New Spark plugs installed
MAF cleaned
Throttle body cleaned
no codes
coil packs good
compression good.
Anyone else having this issue?
