Iam a neebie and need some advice.
Just p/u a 850 sedan non turbo.
The engine has a misfire at idle and appears to go away at speed..
I changed the plugs (autolites) and might have helped minimally..
Just looking for advice at what would cause this other than tune up parts..
I searched the forum and noticed stuff like MAF..Where is the MAF located?
Any sugestions would be appreciated..

Thanks in advanced, Rich

 

MAF is located right after the intake box. I would try a full tune up before trying anything else. And would recommend only using OEM plugs. Also do plug wires and cap/rotor. Once all that's done and if you still have a misfire, go from there.

 

Is CEL on?
Pull codes. That may narrow witch cylinder is misfiring.
