I recently purchased an 87 245, which runs pretty good except for after I leave it at idle. In normal driving, it has a slight hesitation under light throttle, but otherwise runs great. However, if I warm it up and then leave it at idle for 15 minutes or more and go to take off, it develops an aggressive misfire. It is not noticeable at idle, and usually will rev freely in neutral, but barely stays running with any load. It feels like ignition timing is way off, sometimes it backfires too. If I get the car to move after this happens, and apply too much throttle it will try to stall out. Shutting the car off and turning it back on does nothing, however letting the car cool off to ambient temperature and restarting fixes the issue unless I let it sit at idle. What is most confusing to me is that I can take the car on long road trips without issue, but not let it idle. So far Ive replaced the cap, rotor, plugs and wires. Any help in troubleshooting would be appreciated
