So I'm gessing that its going to take a trip to the dealer ???? To tell what the real issue is ?
I hate to say it but I have a poster child jeep it has all the classic issues it has the oil filter that drains back, it has oil consumption , I have replaced the knock censer and EGR still rattles like the old timing chain sound. It belches gas when you fill it up. I had the wobble for a short time. But it still starts and goes where i need to go every day but I really do like that there are places like this where I can ask for advice and for that I that you very much

I would rather push my jeep than drive anything else.

Ok update .... Finally had to do clutch on this jeep so I thoroughly cleaned egr system and replace All the gaskets fixed all the exhaust leaks and had gotten rid of egr codes for a couple of months now..... Yesterday it came back.... Y could I be having all this trouble with egr I have had it to dealer and even they are scratching there heads ... Runs fine except for some fuel ping but I have replaced crank cam & knock censers and I've even gone to a superchips flashpaq .... Any thought will be welcome .
Every once in a wile it acts as if rpms won't slow down when shifting gears too .
Thanks Danny

Other things I have done is to take it to dealer an I had them open computer up as much as there system would allow . For tire size ect. Then I got a flashpaq so I have set all the perimeters to my jeep .... I'm trying out second tune first was 87 tune now going to try 91 today just to see .
Don't know if it matters but but I live at 6700 feet above sea level . And go down quite often to 4500 .
But I still have pinging and egr issues .
If the code pops back today I'll post it Ron .
