it's amazing how such a small thing can **** you off so easily i changed my plugs today and put in a 160 stat and changed the oil today well i finish all of that and start my truck to go for a test drive runnin good till wot it's missing and missin bad on top end but very suttely at idle so i come home to figure out whats wrong well 4 hours later i finally figure out that i have a bad plug. i pulled it out at first and it look like it was fireing but i guess i was just a weak plug put in one stock delco and she ran great. but it was a very frustrating afternoon/evening all because of one crappy plug but i'll replace it tommorrow. but for now it's miller time

 

At least you got it figured out and didn't do any permanent damage (hopefully) Stuff like that can be really frustrating. Oh and have one for me

 

Try driving to the exhaust shop and forgetting to install plug in one bank of the coils.

 

i accidentally cracked 6 plugs one time... that sucked.
