1998 Chrysler Sebring
6 Cyl.
119000 mi.
Just bought this car for my Daughter and have had the following done with no results. (paid $1500.00, but put $695.00 on sales slip to help with sales tax, got boned)
Replaced plugs, rotor, dist. cap.
Checked out misfire Cyl 5, codes PO300 & PO305 found.
Leak down test (Good) for Cyl.5
Compression Test 172
Replace lower and upper intake Gaskets
Swap Injector & Spark Plug 5 & 6 No Change.
I also had to replace the Cat. Converter because it was broken up inside, the guy at the Garage said that could have been from the injector at 5 shooting to much gas and overheating the Cat.
Garage said the computer seems as if it was replace at some time because there is a sticker on it that says it has to be programed and New cars do not have these stickers.
He suspects a wire could be the problem but says it could take days to find it. I'm already into this thing for $1200.00 (parts & labor) on the of the $1500.00 I paid. Could someone point me in the right dir. if I were to trouble shoot the wiring myself. I do HVAC so I do know something of wiring.
Thanks

It would help if you descibed the problem history a bit more .Does it misfire all the time , or hot , cold , under a load , at idle only or at speed too . When did it start ? With what you have given us I would guess : broken valve spring ,bad lifter ,cam lobe worn .

I see in your post you didn't mention changing the spark plug wires. try switching wires with a known good cylinder and see if the misfire moves off of #5. Also, which 6cyl do you have? Chrysler has made a few different ones and knowing the exact one helps us out a lot.

It only misses at an idle and after it has been warmed up for 15-20 min. It runs fine while driving. My Daughter just bought the car and the guy said he was going to help out by writing it up for $695.00 instead of $1500.00 that we paid, got boned on the deal
