Engine Performance problem
2006 Jeep Liberty 6 cyl Four Wheel Drive Automatic 47000 miles
The engine light comes on periodically and the engine " stumbles" and sputters, hesitating for a while. Was in shop twice for the problem. First time they could not replicate it and felt it was a gas problem. The second time the electronics system diagnosis was " multiple misfires". They deemed it necessary to R& R intake valves and keepers, grind exhaust valves and lapped. Also removed squirrel debris from airbox and intake. Very expensive. This was in February. Now exactly the same thing is happening- sputtering, stumbling and engine light.
Any idea what is really going on?
