Re: Misfires - '02 JGC Limited...

So best is to start with the compression test when time allows to see if the problem is there. Keep us posted.

Wink Re: Misfires - '02 JGC Limited...

have you checked the camshaft position sensor, had the same codes on my 99 with 4.7 try taking out the cam sensor and cleaning the end off and putting it back in. if it works for a while (longer than it does now) then replace your camshaft sensor.

Re: Misfires - '02 JGC Limited...

First off, if you know you have a major misfire, STOP DRIVING before you do more damage.

Its very possible that you have either a bad cam or crank sensor. If it isn't that....It would most likely be a valve issue.

I have a still good (although old) cam pos sensor....let me know if you'd like to buy it for the sake of troubleshooting. It takes about 10-20 mins to swap out.

Front/bottom passenger side cylinder head.

It's held on by 1 10mm bolt, when the bolt is off , wedge a screwdriver in and yank it out.

You'll need to be under the truck to yank it out.

Re: Misfires - '02 JGC Limited...

So... I'm a bit skeptical yet... But seeing noticable engine happieness.

I removed the sensor.. Cleaned it off well with a papertowel.

I noted some oil in the connector.. It hadn't leaked down the side. Must have come thru the sensor. I'll replace it later. But in any event. Cleared the codes.

Cross your fingers..

Thanks for the ideas guys. I'll let you know

Kyle

Re: Misfires - '02 JGC Limited...

well... just cleaning it didn't solve the issue, i will try to get the new sensor in tomorrow b4 i leave for Haiti. Really getting sick of all the false positives.. that sort of gives you the idea of its intermittence.

Re: Misfires - '02 JGC Limited...

Hey Kyle,
Fellow Georgian here not too far from you. Got my 02 from a kid up in Dahlonega recently.
I'm staying tuned to see what your problem is. I've been having computer probs. Just received my 4th warranty replacement for a "rebuilt" computer but haven't installed it yet.
Best of luck!

Re: Misfires - '02 JGC Limited...

Update:

finally got back from Haiti, Reno, Albuquerque, Salt Lake, Denver, Harrisburg, and New York.

Well.. its at the dealer now.. they don't even know what the problem is with the first $100... now they are on to the compression test. another $100. and that's just looking at the problem. not fixing it.

best guess.. its a Piston Ring Problem, or a Valve Problem. ($&%@!!)

Kyle
