backfiring on the highway
backfiring on the highway
My car seems to backfire or jerk when I'm cruising on the highway, usually between 1500-2000 roms but also over 3000.
Timing is set right at the line in the balancer. Any ideas?

I lost an O2 sensor one morning driving to work. The computer leaned out the carb so much, I had a "trailing throttle backfire" out the exhaust. It was also surging during cruse, and very lightly pinging going DOWNhill!!!
