John, thanks for the response. I already bought some NGK laser platinum plugs. ALLDATA calls for NGK BPR6ES-11.. The ones I have are FR5AP-10 and they cost more because they are "Laser Pltinum" (not sure what that means). Should I take these plugs back and get the cheaper ones.?
Ok, here's a good one. I bought the exact plug recommended by ALLDATA. These plugs take a larger diameter socket which does not fit in the hole. The old ones were 5/8 and these are 15/16. now I'm confused.
What do you recommend?
John, sounds good. those are the choices I have in the Chiltons. I just took out all the old plugs and looked at them. They are al worn and the gap is ..055 instead of .040 - 043. I will definitely have to replace those. I notice one cylinder had some brown guck in there. Looks like little water may have got in when I had the engine cleaned. I cleaned out the channel and put some dielectric on the plug and reinstalled all the old ones just to see. The car runs perfect now with no codes. Thanks for your help.
