Hey, I had been too busy to try setting the timing in the Olds, between my job, summer obligations and working to get the frame rails in this car. I did set the timing tonight though, per Ron of Chicago's suggestion. It was 10 to 12 degrees off!!! Needless to say it runs WAY better now...smooth accrleration and no back firing. Thanks so much guys. Al

<span style="font-weight: bold"> </span> Hey thanks for the response. I'm not looking to set the dwell on the MC solenoid at this time, just to check the ignition timing and the emissions label says to ground that circuit. I seem to remember a tan and black wire that bypassed the EST for the purpose of checking the timing. I can't seem to find it under the hood. Like I said though, that was 20 years ago. Btw, what MPG does your well tuned 307 get. My 70 Charger with a 383 gets around 16 if I go easy on it. I'm thinking (hoping)the Olds should do better. Thanks again!!! ps:sorry about the trans

Hey guys! I've been reading on this forum for some time and just signed up tonight. I purchased an 88 Cutlass Supreme Classic last fall (always loved those G bodies!) and I'm trying to get it going for the summer. I'm in the process of doing some body repairs (rear frame and lower quarters in front or rear wheels) with parts I cut off another car. It also has some drivabilty issues that I'm working out. I've made a few repairs, but I want to make sure all the basics are covered as well, which brings me to my question. In order to set the timing, the emissions label says to ground the C3 diagnostic lead. Where would I find that? I bought a Factory Service Manual at a swap meet only to find out, when I got it home, that it was for a FWD W body. I also got a Haynes repair manual and while it offers some good info, it doesn't address the C3 diag. connector. I worked at a Pontiac dealership in the eighties and seem to remember a lead coming out of the harness near the firewall. I don't think it was a G body (Grand Prix) though...likly a FWD...hard to remember (that was many beers ago!!) Anyway, hope someone can help me out. Thanks. al
