Here are the symptoms;
1. Starts O.K. and then as you accelerate, it goes very lean. The valves ping like a champ.
2. As you continue to accelerate, the pinging goes away around 2500 rpm. It bucks like the proverbial bucking bronc when it is in the lean condition.
I have replaced the following;
new factory plugs,
D.I.S.
new hot coil
new camshaft sensor
new crankshaft sensor
new IAC
new Motorcraft battery
cleaned the cold air cleaner filter
brand new gas
new coil pack
new fuel filter
Additionally, I had the gas tank dropped and checked the gas line and it is where a good pick-up should be.
The problem started after I had driven about 2k miles after I did some refreshing of the engine systems.I did remove the blower to get to the valve covers to replace the valve cover gaskets. I spent a significant amount of time checking to avoid vac. leaks.
Am I on the right track by checking the fuel pressure "under load" ? Also, to re-check the I/C sealing areas and the blower sealing areas ?
Your assistance and comments are appreciated.
