Re: First Start Issue - '97 Bathurst
Update to the thread. The MAP sensor was ruled out, the car still stumbled with the borrowed sensor - no improvement. Stumbled 4 out of 5 starts.
Circuit Opening Relay: I have had 10 good first starts in a row since installing the new Circuit Opening Relay (10th start being this morning). It's the best result I have seen with any testing. While not 100% indicative that the issue is fixed, it's a good indication that it could be the solution.
