Default Re: Help!!

Chad, a couple of years ago I asked about that and was told it was illegal for SS. I have wondered about a simple capacitor to try to dampen posdible voltage spikes. Pete Peery says he has a microswitch not open cleanly so it was bumping the 2 step again. I waited too long last week to find another microswitch and the problem was still there at the track Sunday. New one on it now, just looking for more things to look at before I take it back out Sat.

Thanks.

I had an intermittant miss in my SS car. Drove me crazy,tried everything.Turns out it was the microswitch in the TB button. The vibrations would make it activate the 2 step. I replaced the switch and mounted the button on rubber to try to isolate vibrations.

Question Re: Help!!

If it's only on the first pass of the day, perhaps it could be something related to the carb/jetting/vacuum signal. It may be momentarily too lean because the engine isn't "heat soaked" from previous runs and bogging.

now you're gonna have Ed searching all over that LT one for a CARBURETOR. I know he's old but don't mess with him like that, lol.

Red face Re: Help!!

lol Oops. Well, he didn't say what he had and I didn't know.
But the theory is still the same - momentary lean. Don't know what may have changed from before the problem appeared. Just a possibility to consider.

You have probably already checked this but pay close attention to anything going thru the firewall even if thick grommets are used. I have helped chase this stuff down on several cars that only happened on the leave and only for what seemed like milliseconds. Very small nicks not readily apparant to the naked eye. Seems that the offshore grommet sources quality control was lacking.

Ken may have it. Pete Peery told me the same thing. I have a new microswitch on it now, maybe it's fixed. It's the only thing I didn't get changed out last week. Self employed, but you would think I could make a run across town to the electronics store to pick one up. This semi-retirement ain't very "semi" yet. Still busier than I would prefer. Got a new switch this week anyway. Two guys that had the same issue with the switch makes me feel a little more confident.

Thanks guys!
