Bump. Hoping for a miracle...

o.e.m

Update. The jeep started misfiring and we took it to another mechanic while on vacation. They had it for 5 days and came back with the PCM again. I replaced the PCM and symptoms still exist. Wiring looks good. Fuel pressure ok. When I replace the PCM the check engine light comes on...

it could also be that the old suspension had 150k on it:)

I currently have these installed on my wife's liberty. Ride is more rough than OEM

Replaced PCM and problem still exists. Jeep runs fine until you hit 2.5k RPM. This is super frustrating. Any sensors anyone can think of??

Answered my own question. As I suspected, the suffix is software updates.

Happen to know if these are interchangeable? like 56044208AF can replace a 56044208AG? or did you order an AG and receive an AG? just an example.

Back to the original question, does anyone know if you buy a PCM with P/N 56044208AF and your P/N is 56044208AG. Will this still work? Im in the same predicament. I've checked everything and last thing is PCM replacement.

Took it to an indy shop and everything checked out ok. Anyone know a reputable place to buy a pcm?

replaced the suspect fuel injector and all o-rings. it was a ***** getting those out. Problem still exist :( any other suggestions?

spark plugs were swapped and issue still exists. Tried fuel injector cleaner to no avail.

My wife's 2004 liberty sport has 170k. After changing all 6 coils, I am getting some weird engine malfunctions. Codes are P0204(#4 fuel injector) and P0304(intermittent code. #4 misfire) resistant on the fuel injector is good and the issue exists in the same location after switching...

I never had it on the bench. That was someone else. The shaft will seat into the locker but only about 1/8 of an inch. I thought it was the lock ring so i removed it but still no luck. Since it came out after a few yanks, using a hammer is my last resort :)
