SILVER Star
What is the AFR doing when it runs rough?40 died waiting on the road construction traffic signal on the MDH. It had started idling rough going down into Silverton and hoped I’d get lucky and make back into Ouray. After graciously being towed back to Ouray (Thanks again!!!) , I determined it wasn’t getting any spark using timing light. Pulled the distributor cap and the Pertronics sensor was black/burnt. Luckily had a spare, and quickly had it swapped out. It now starts and runs fine for a couple of minutes and then starts missing and idling rough. I took the distributor cap back off and raised the rotor about 1/8” up the shaft, reassembled and it keeps doing the same thing (runs fine then starts missing). it seems maybe the rotor is too short for the cap although I don’t know why it’s ran
fine all this time and now just started acting up. Open to thoughts or things to try!! (and stranded at our Vrbo in Ouray)
(I’m running a sniper, but I’m pretty sure it’s ok as I can see a steady stream of fuel flowing when the engines running. guess it could possibly be a O2 sensor?)
