so i did my huge tune up on my 302, fuel filter/air filter, plugs, cap and rotor, and the coil.....


the cap/rotor are pretty nasty seen in pic below, and oh my god these plugs were f'ed up.

one plug was an "#1 in the picture" autolite 25 which is what i replaced them all with and it was even gapped right about .052. dig this though the rest were boush platinums and 2 at .036 two at .039 and the rest at .040. one of the platinums however "#2 in the pic" is so corroded that there is no more gap its all white deposits sealing off the gap as seen in pics below.

moral of the story i guess nothings right unless youve done it yourself, anyway i guess i found my idle issue hahaha, she runs like a dream now and lots better response as well as power.....

 

I'm suprised it ran, lol

Glad to hear that you got it figured out.

 

FORD trucks will run on cow manure

 

Bosch plats SUCK!!!! My tech refuse to put them in any vehicle.

 

i agree w/ all above posts. lol

 

What do you think are the best NGM?? I've always heard that the NGK's are one of the best but I've never had them.

 

ive ran autolite 25's in my mustang gt now for 4 months and they are the best plug ive used, thats why i used them in the truck and once again superb results....

 

my cap looked the same way on my 351 in my 89. the plugs and wires were worse. one plug cumbled in my hand and the wires were just straight up shot

 

man thats messed up.... on mine mainly i was just mad someone even put platinums in a ford 302, but yet leave 1 of what should be in there, and of couse these bosch platinums were supposed to be pregapped, so i bet thats why they were all bs. always check gap even on pregapped they are never right. damn people, hahahha

 

You may want to check the new plug that you put into the cylinder that "plug 2" came out of. You would have probably heard it but there could have been a carbon deposit on the piston that bent that plug. That or the orginal installer was a moron like you said.
