This is the second set of Autolite HT1 plugs I have gone through. The Tune shop said I need to gap them to.024 how can this be done with the design of theses plugs?:headscratch:
What keeps going bad with the plugs? If you are having problems with the HT1's such as porcelain damage, you probably need to run an HT0 as your engine is F/I. A gap of .030"-.032" seems to be about the norm.I have them set at .033 from the Tune shop and they keep going bad. I just wanted to be sure that they were not going to bang the with a hammer.
[B said:mineralgrey[/B];1003336]They gapped the plugs but I didn't get back to read the comments. I hopethe guys at the Performance shop knowwhta they are doing. I put them in and the same problem exists. The rough idle and stalling on take off. One plug has oil residue on it but they plug is firing. What can cause this. Maybe the injectors are clogged?
