did you run any octane boost or race fuel? someone brought a mustang into a friends shop a while back that put 104 in to go faster and killed the plugs and o2s.

Nope...in fact, the plugs did not look bad either.

sounds like you fixed the problem anyway. plugs do have to look bad to be bad. Did you replace with platinums or coppers?

Well, you may get a chuckle out of this answer. Went to my Ford Dealer on Friday to buy the Motorcraft Platinum. They sold me plugs for some other car, not my Mustang. So, went to Advance Auto Parts on Saturday and bought the Autolite platinum plugs. Can't wait to visit that Ford Dealer at lunch today and stick these plugs up somebody's ***.

I think those are for the FRPP heads.
AWSF-32c or p would be the platinums or coppers

So, I guess this is why the new cars have all those weird engine covers now?!

To keep dirt and moisture out of these electrical components.

Googled the part# and found references to it being used in the Contour and the Mercury Villager.

AWSF32c is the correct copper plug, I know AGSF-32c is for the FRPP heads so I guessed that his may have been a platinum version of the same FRPP plug. I still like going to walmart and using the Autolite 764s.hopefully just an honest mistake by the counter guy.

Well, just got back from returning them. Told the guy (different guy) what happened. He said that they were the right plugs and they just look different.
"Says it right here on the screen...plugs may look different...didn't they tell you?" Um, no.
Then he tells me that Autolite plugs are the worst spark plugs you can put on a Ford...WTF?! "Why?", I asked.
"Because they're just like champions and they don't last very long.", he says.
"Whatever, dude. Just give me my $68 bucks back!"

Time to find another Dealership.

$ 68.00 for plugs..........
Any copper will not last as long as a platinum.
Don't buy from a dealer unless it is not offered anywhere else. Some things like belts, hoses, friction modifier are reasonable and sometimes cheaper at the dealer, at my dealer anyways.

Incorrect, AWSF-32C is the old part for stock heads and AGSF-32C is the updated part for stock heads. You cannot buy AWSF-32C at the counter any more, only the new part... And the C means copper (P-platinum, PP-double platinum).

BTW...don't wanna keep this a secret. The dealer was Castrucci Ford, Highway 28, Milford, OH, 45150.

Which finger do you think the little dude is waving?

I heard from a reliable source that NGKs are the way to go... anyone else agree or disagree? I'm getting ready to replace my plugs and will probably not go with platinums.

Thought my problem was fixed, but it ain't. Still hesitating at WOT. Taking the car to the shop that installed my gears and pulleys next week.

Well, I decided to try one more thing before taking it to the shop. Replaced my MAF a few days ago. Today was the first good test b/c I was in stop and go traffic and then sat in a drive thru for 15 minutes and then drove back to work on the highway. It got pretty hot today...like mid 80's I guess.

Problem seems to be solved!

I thought I was on the right track right after I put the new MAF in b/c the car was idling smoother right off the bat.

When you buy the MAF, it includes both sensor and housing. Replaced both to be safe. There was a 75.00 core also.
