Happy Easter! Cheers to new beginnings!
I've discovered a "new" problem with the 76 aspen. I thought after the engine was good and warmed up that I was having an AF ratio problem.
Then last night when putting the car to bed I shut off the head lights while backing into the garage. Suddenly it ran much better.
I mean it went from barely running and hard to apply throttle without flooding it to responsive and returning to the set idle.
I pulled forward and checked under the hood. It ran beautifully. I even turned on the headlights and no difference.
So, is it an alternator/regulator issue? Or maybe a ballast resistor/coil issue. I wasn't able to reproduce the problem in the driveway. But in hindsight, it's been happening after a drive of more than 20 minutes.
Anyone experience a weak ignition problem after driving for a distance? I'll keep my DVOM handy for the next time it happens.
As always, I appreciate any ideas/input.
