before i put on a blower i had good luck with bosh platium 4's vs other brands (autolite,ngk.) they stayed clean the longest.iridiums are just a waste of money but the ricer guys just love them since i always see them list there spark plugs under there list of mod. hahaha. also if you are looking for cop's if have all 8 listed f.s. if anyone is interested. all worked great and the had 45k miles on them before i went with an msd ignition.

When it doesn't start, it makes no difference how long you crank it for because it still won't start. You have to quit cranking on it and try it again to get it to start. Usually starts on second try. Thanks for all the help.

Just wanted to let you guys know that I had mycar put on the computer today and it says that coils 1 and 5 are bad. Both showed missing at some point or another. I will also be replacing the plugs when I change the coils so hopefully I will be able to get the miss out of it completely. Again thanks for all the help. As for the car not starting sometimes, the idle air control valve showed to be bad also, so hopefully that will fix the starting issue.
