Needle seat question

Bigal442:
Yep, not looking forward to changing the plugs. Having headers and AC on the car won't help either. I might have to reach out to the Vette community for any tips or tricks before attempting.

Any chance those plugs will go back to "normal" over a period of driving after I get the fuel and ignition dialed in?

when you get those plugs to clean up . let me know how you did it. ive never been able to get on to work properly once they had a lot of excess fuel.

Bigal442:
It may be a while before the weather and the streets allow for more road testing. I was thinking I would replace one or two of the easy plugs and then see how they do after some miles before I go after all those harder to reach plugs. It sounds like some of them will be tough to get to. Some are accessed from below and some through the wheel openings along with some special tools.
