Thread: Engine cutting out??

also souds like spark is being blown out by boost

sounds like a spark plug problem over gapped?? I had a similar problem, good luck on finding the problem.

ok so I replaced the plugs, and she runs a lot better. The old plugs were leaning more towards a white color, and the little white thing around the electrode (The ceramic thing or somethin) was A light brown color, and one was a almost red color, with white on the bottom of the plug. What does this mean? I dont want the new plugs to go through the saame thing you know?

I am pretty sure you guys were right with the boost pressure blowing out the spark, and they WERE over gapped by like .010 of an inch. Gapped new ones to .044. Should be set for now, just wondering about the condition of the plugs. Thanks!

.044 still too much gap in my opinion I gap mine at .038

if this car is turbo, start with a gap of .28 and see how that feels, if its turbo, you can get hesitation,stalling,cut out, problems from the boost coming in stonger than the spark and blowingthe spark out (your original problem) gap them smaller and go from there most TURBO cars run on .28-.32 for best performance and problem free. depending on your iginiton setup
