Spark Plug Question

[Redog]

I have the Bosch Platuum +4 in the car right now and I still have that cut out problem, I also have a few misfires.

Are the plugs the cause of this? If so what should I replace with :unsure:

NGK v- power or iridium
AC Delco rapid fire.

I did the search on this board, and they were the plugs I got. Plus it's been 30,000 plus miles since I swaped them

yeah i talked to you earlier about this. i could of sworn i was the one who told you the +4's will give you nothing but trouble. NGK and AC delco will fix your problems i bet. B)

Yeah when I get the heads done I'm getting new plugs ;)

The Bosch plugs will eventually cause the puter to throw a code due to the frequency of misfires. Go to a GM dealer and for free they should hook you up to their hand unit and you can see the frequency. Delco will correct this - others I have not used.

Where can u get AC Delco plugs from? non of the stores around here have them and the dealer wanted 9 bux a piece!!!!!! are they really that expensive?

Got my AC Delco Rapidfire #14's from www.rockauto.com for less than $4 a piece.

Yo Mfuller how and were have you been??!!

Is #14 the size?

[mfuller]

I've been swamped at work - it's nice and keeps me out of trouble.

Anyway, the part number for the plug is 14. Be sure to check the gap before you install them.
