Hello 95tealvonvert, your C4 sounds awesome. Glad to know I'm not the only one who celebrated the 50th with a corvette.
Thanks for the tips on cleaning and maintenance. So far I've flushed the coolant (dreadful muck came out of that) It has fresh oil but I have not done anything with the break or diff fluid. I'll look at that next. I did change out the plugs. The old ones were a bit fouled out. We'll see how she runs with the new plugs.
Thanks once again! fan66
