I'll try and make this short....

94 Cougar, 4.6L (Friends car in my garage), It was running extremely rough, smoking out of the exhaust (I fogged the neighborhood driving it home) and gas was pooling up and running out of the exhaust pipes/mufflers....

I changed the MAF sensor, changed the plugs, etc... It still runs rough, but the smoking is pretty much gone (except for what i thought was still in the exhaust)...

I have come to the conclusion that it is fouling the plugs on the right bank ONLY, the left bank is fine.....

The compression in all 8 seems to be right at 150psi, so I am assumming that timing is not an issue....

Any one have any thoughts????
