part throttle stumble?
My engine has a stumble under part throttle when it gets hot around here and I can't tell why. Its been tuned correctly and the plugs look good, also my a/f gauge says the ratio is good.
The only time it acts up is when going from a stop and you just get on the gas, it stumbles. Once your going theres no problem, and if you start from a stop and give it a good amount of pedal then theres no problem. Any ideas?
