Craig,
To be honest I'm not having an issue with the Jegs coils that I can put my finger on. It's just that the car don't seem as crisp on the gass and I have a slight shake....can't get the nickle to balance easily & consistantly....at idle.
The scan is clean. I got RC's & magnecore 10mm wires, new plugs, PCV's & the rubber, no under plenum vac leaks out of the 2* system anywhere. Pump runs for three seconds, maybe five on start up and then never comes back on, ever. Battery is up to it, and the alt is maybe a bit questionable..I have to do some more testing on my own. I got the OE/replacement coils so I figure to do them when I swap to my ported stuff. What the heck, they're right there...
Ya know when you think "Damn, it's just not sharp. Eh, what the heck is it?"
The only joker in the pack is the Jegs coils, and the somewhat questionable reputation of the aftermarket stuff vs the real OEM stuff for the LT5's application...you know we are the only motor to have coils living in hell!
Tom
