Sure thing. To date:
- New distributor
- New NGK Iridium plugs
- New NGK plug wires
- All new injectors and seals
- Replaced a bunch of vacuum hose and can't find a leak with my current test methods (smoke)
- New fuel pressure regulator
- New fuel filter
- Throttle body cleaned
- MAF cleaned
- Throttle Position Sensor tested working
- Throttle wires adjusted correctly
- Timing double-checked and steady at 15 BTDC
- New gas cap
- New air filter
To re-iterate, the stumble does not happen at idle or under full throttle acceleration. It only seems to do it when my foot is barely to lightly on the gas and only between about 2500-3200 RPM.
