So after being without my car for a month due to a vacuum leak on #2 cylinder, and then rebuilding my DRLA's, I spent monday tuning the car with a quick test drive, and then drove for about an hour and a half yesterday without issue. The car was fantastic on back roads and on the interstate. All the while my head temps and AFR were spot on perfect. I was stoked to be back on the road!
I go to start the car today, and of course, the AFR is way off to start. I figure I'm just going to have to tweak the carb sync a bit. Then as the car is warming up I see on my 4 channel head temp gauge, that cylinder #3 is conspicuously cold. The other cylinders all come up to their normal operating temp, but #3 is staying around 200 degrees and won't go warmer. The engine itself sounded 'off', like that cylinder wasn't firing. I tried changing spark plugs. Nothing. I tried blasting out the idle circuit several times with compressed air from both the idle jet side and the mixture screw side. Nothing. What else can I try? I don't know what possibly could've happened overnight for this to happen. The car sat in the garage untouched. |
