Getting a rough idle problem after the car has warmed up and is idling. Engine sputters and almost quits. getting trouble code p1399 (random misfire) sometimes and once I got trouble codes for cylinders one to four misfiring. Tried changing plugs but it did not help.

This is a common problem with that many miles the MAP sensor is off but not enough to trigger a check engine light it effects the mixture which causes the codes. I would replace the MAP. Here is a diagram to help you see what you are in for when doing the job.

Here is the location on your car. Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.

Cheers

This thread is spot on. I took my car to my mechanic and he could not figure out the problem. This site rocks!
