I agree. Even if your CEL isn't lit you might still have codes stored. Definitely check them before you spend any time or money doing anything else.Is the CEL lit? I'd try pulling the codes first and see if any shows up.
Ford probably put timing marks on the crank for diagnostic purposes; you can still check the timing even though you can't adjust it. The ECM uses inputs from the CPS, TPS, MAF and MAP to set the best timing for any given engine load.Yeah same here thats the closest i could find also? So why does it have timing marks then? I'll try another store. peace

Any luck on the code? I still can't find a definition for a code 90. Those are generic codes though, and I can't figure out why one number (90) would be skipped.....?
It must mean something, maybe a factory testing code....?
Since it's in the number range to be O2 sensor related, you might try checking the sensor wiring to make sure it's not burned from the exhaust manifold, loose or broken.....
If you're good with a multimeter, the O2's not hard to test, just 3 wires to check on a 92.
Replace your ICM (Ignition Control Module) and I am sure it will stop. I had the same thing happen to mine a few years back. The ICM is about $115 and located on the lower intake manifold.
