Dirty Back Bumper

[Fryday13]

Hey ive recently been lookign at finally investing in (cheaply investing in) a 2 door turbo skyline. Ive found one right in my price range but says that allthoguh it runs he thinks theres a missfire and the rear bumber above the exhaust is essentially now black. Im happy to do some work on this car to get it going right but is it going to cost me an arm and a leg to fix it if anyone knows what might be up? I figured the two things may be related

Need to drive and to see if there is a missfire, or it may need a tune up

[Fryday13]

If it is, what sort of money and work is involved in getting it straightened out?

[markdem]

shit can be removed with paint cutting compound or other forms of abrasive stuff

[Hadouken]

Misfire could be almost anything.

Spark plugs - $30

Coil packs - $300 - $1m haha.

Or could be something more sinister.

Ha it wasnt the cleaning that worried me it was the expense of getting it fixed. Guy had sold it elsewhere anyway. but cheers for the scary knowledge about coil packs!
