First post and new owner in the world of Porsche.
Bought a nice example with great history and hoping to get plenty of use out of it however there is a problem to over come first. Isn't there always!!
Started with a flashing CEL which would become a solid CEL then would disappear. This would repeat over the last few days.
Clear misfire and showed to be cylinder 4 from a simple diagnostic machine.
Changed the spark plugs and coils but not fixed the problem, so I'm hoping for some advise on the next steps please. I could send the car off to a specialist of course but am fortunate to have plenty of space a ramp and every tool required to carry out the jobs. Plus I enjoy playing with cars.
I would like to carry out a compression test but do any of you knowledgable people have any suggestions of things to look at or test first before the more intrusive investigations?
Any help appreciated, thanks.
