Frustrating engine problem!!
I have a 96 NFII Ford Fairlane Ghia V8 which I got off my grandfather. Its only done 84k km and as such, a few things died on it as soon as I got it.
At the moment, I'm having an issue with the way it drives.
Its very sluggish, slow to rev, and pumps clouds of black smoke out when I put the boot in. It only started doing this once I fitted a K&N panel filter.
If I come off the throttle a bit, it runs better...but as soon as its full throttle, it runs like crap.
The exhaust also smells like rotten eggs, which I think is due to the fact the cat is dying from the engine running so rich.
I cleaned the AFM which was covered in black crud, and it ran fine for about 3 days, and now its back to the way it was. I have yet to pull the AFM again to check it out.
My theories on this problem.
K&N throwing filter oil onto the AFM, stuffing the reading up
Plugs and leads are gone (leads look to be original, plugs arent)
Has anyone had this same problem before? If so, what was the cause??
Any other ideas??
