Do these spark plugs look bad to you? My car is bucking and cutting out horribly under acceleration. Not to mention it has no power what so ever now. Are these plugs the culprit? Thanks in advance!

 

They look normal to me. Book says they should be light tan or light gray, which yours are. Check gap and if possible see what color the spark is when it fires. Bright Blue/Blue would indicate good. Yellow/Orange would indicate bad wire or coil. Do so with either a new plug, or an inline spark tester (this being the safer option).

 

Thanks for the quick reply

They look fine, according to their color. That doesn't mean you don't have a "bad" one though. How many miles are on them?

 

Thanks 69!

 

one on far left looks like it may have something going on

 

yup just how mine looked the best ,when we did the headers pulled them ,could be the wires,it says you did headers did you get 90 degree wires ,did you change the wires ,I had to replace mine couse the old manifolds are in there own way on mine ,not sure about your v6 though

 

My plug wires are about 2 months old.
