Hey guys. I have a 92' ext. Cab with the 5.0, 4x4 , and Mazda 5 speed. I recently changed the spark plugs and wires because I was getting an engine code for cylinder 8 malfunction. The sound I get is like an exhaust leak but I only hear it while underload? Any suggestions?

 

You already have a thread started for this issue: https://www.ford-trucks.com/forums/1...etonation.html

plus others you found along the way. I suggest you stick to one thread.

There is no Diagnostic Trouble Code 8. That is the code that is flashed to indicate you have an 8 cylinder engine.

 

Ok. Sorry about that how do I go about deleting this thread.

 

It's easier to just stop posting in this one. A moderator can probably delete it, but you have to find one.

I posted the link to your other thread so others that may want to help you out can go to the other thread to see what has already been done and reply there.
