Could a O2 sensor or both be causing this??? It's ONLY at very slight throttle up to 2400 RPM. Any hard throttle or past 2400 and it's fine.  |
Vacuum leak possibly.
I have seen similar with O2 sensors. Even had a friend whose sensor coupler got burned on the exhaust such that he could plug it in wrong. He chased an intake backfire for weeks.
