Is this a normal characteristic or any idea what is going on here? Cruising 50mph or so and depress clutch and go into neutral, Engine surges and sometimes stalls. I happened to notice when this is occuring the stft will abrubtly max out adding 29.7% right after even though o2s and wideband both agree that it is already a rich condition. I have reset the fuel trims and retested with same results. When I keep it out of closed loop it is okay so I think I am on the right track just have no idea why it would be so drastic with the stft.
