I would do O2's before dizzy. The motor runs, it just pings like mad. that rules out the dizzy.
Make sure after you replaced all those components you disconnect the battery for about 10 minutes. Otherwise the computer will be using the old info that was stored from before.

Do these cars have 2 or 4 sensors? And if 4 would you replace all 4 or just te front two? Also where is the exm ground? Also it pings like crasy but now it has that high rpm miss and te tach is acting screwy and someone said it gets its signal from the dizzyand its pretty hard to turn when its put of the enginethats why i was approching the dizz beeing bad

the 5.0's only have 2 O2's before the cats. Although some parts houses will try to say there are 4. just get the front O2's if asked.

IDK about the PCM gnd.

Ok well i just drove to st louis the problem is get substantually worse base timing @ 9 and it spark knocks even under light acceleration still with the misfire on the top end check engine cam on for a hot second on the way up here im goin to pull the codes when i get back to town but at this point i dont think i can take much more timing out of it and it be anywhere neer drivable

Okay, O2 do not last forever. Maybe 60k miles. The PCM doesn't use old codes. It will log events but it relies on the voltage signals from the various sensors as the are processed by the PCM while the car is running. The motor running does not rule out the dizzy. Bad bushings/bearings may affect the PIP signal to the PCM. If the PCM isn't getting the correct signal total timing could well be off enough to cause pinging/detonation.

On my way home last night the pinging is intermittant without reason i meen as much as a few block diffrece im pinging at 1/3 to half throttle lite acceleration to a few blocks down the street no pinging at all im goin to do the grounds ronite and also try a diffrent ecm and see what that does
