98 pinging
I have been reading the other thread on the '98 detonating problem, which mirrors my own problem. I have a 4.6 w 123k, so a plug change is in order. I want to know what plug to get( not copper), I don't want to change my plugs every 20k. I have sprayed the MAF, but where is the DPFE so I can try that, but I must admit after reading the other thread about reprogramming the 5.4, to solve this problem sure sounds like the ticket.

I have a 98 4.6L and it's running fine on 87 octane.I had some pinging before as well as a check engine light showing lean on both banks.I cleaned the MAF with electronic cleaner and reset the computer but got the check engine light again a week later.I then used throttle body cleaner on the MAF(sprayed the hell out of it).No pinging or check engine light for the last 3 months and going.Also,I didn't appreciate the know-it-all with the ultra-confident and smirking face at AutoZone(who reset my computer for free) saying I needed to change all my oxygen sensors because that was all it could be and he'd been in the business 17 years.Beware.

The thread I was referring to is mentioned in another thread on pinging, the guy said it was in the 97-03 section. The same thread" 98 4.6L still pinging", I have been Keeping an eye on. They mention about re programming the pcm,which sounds like the way to go, but it seems everyone thats doing it has a 5.4 (good for you ,grberglund), I'm waiting to see if it works for a 4.6. I have to run 93 in it to stop the rattle, but I don't get a CEL,Let me know what you find guys. thanks
