    Don't buy cheap plugs

    This is why you don't buy cheap spark plugs. I was getting random misfire codes in the GTP, so I pulled the plugs and this is what I found. Number 3 and 5 are toast.

    I tried accel u-grooves when I first got my truck. The whole ceramic insulator along with the electrode broke off. So the plug was completely hollowed out. Still ran alright with new ngk's after. The cylinder may be gouged to hell when I take the heads off though

    Wouldn't call delco's cheap plugs...maybe you have some detonation and it's not the plugs fault. Doesn't delco make NGK's?

    i think that they do...either ngk or champion. i do know that autolite makes motorcraft...not that that has much relevance here.

    and by no means are delcos cheap plugs. they retail on average $1 -$2 higher per plug across the board of comparable plugs.

    What I was thinking ^. When did a AC Delco plug fall into the category of "cheap" or a bad plug? I think the GTP has other issues.

    That may be possible, if it destroys these plugs (Autolite 104s), then I'll look into finding out what the bigger problem is.

    After the plug change though, I went to work, and on the way, the car accelerated a lot better, and actually broke 140 without batting an eye...in the past few weeks, it's been a struggle to get to only 125.

    Like I said, it pulls really hard now. As a comparison, I barely beat a riced out 3.4L Grand Am last night...it was pitiful.
