We got the SC back with the new paint on it and it is an excellent job. Wind screen out, front and rrear lids off during the process. Now, we have a running problem. It sat in the shop for about 3 weeks and when picked up it will not idle and has a slight miss up to about 3000 rpm. 3000 to redline it seems to run normally strong. I did not see any wires or lines off/loose. Spark plugs and dist cap look good. I checked all the fuses. My guess is that it is lean in the lower rpm and maybe lean thru the whole rpm scale. I am going to try some injector cleaner tomorrow on the freeway. I have the manuals. Any guess as to what may be a quick fix?? (yeah I know, take the new paint off tee hee)

Does your car normally sit for 3 weeks without use or is this something new?

Usually driven at least twice a week. This is a new problem. Fuel was about half full with Chevron. Location So. California.

I'd also check/change the fuel & air filters - test the fuel pump perf, too . Is the batt & charging sys operating to spec? Interview the shop crew - how many miles did they put on the car, did they put an elect charge on the chassis, did they know how to start an SC properly, etc. Taking a car to a shop is like being in a hospital - there's always the chance you'll catch something new (& they don't fix the original problem, either) - sometimes it isn't even their fault. good luck.

I have had two problems come up after painting. One was a ground that was disconnected during removal of exterior parts. One was cut wires that were abraded by a stick being used to prop a hood.

I would also check for intake leaks and disturbed or old plug wires. Look around areas where masking off occurs, and consider a top up with fresh gas and some techron. Go for a nice long hot run.

PROBLEM SOLVED. New plugs, battery plus side not tight, and gas cap not tight. Wish I had done them one at a time--- I suspect the battery was the problem as I dont think the gas cap was an issue like on later cars..

Must see photos of new paint to properly diagnose (ahem- after the fact).
