Yup. I even went back to the stock sttage 2 tune w/42lb injectors and it still stumples for 2-3 seconds before shutting off. Any ideas?

Mine does this sometimes actually. I noticed it when I was backing it out of the garage to wash it, I turned it off and coasted back the rest of the way and it seemed it stayed on and stumbled a little bit before fully shutting off, yeah about 2-3 seconds I would say. I was wondering what was going on. Normal maybe?

Interesting. Thanks. Anyone else experience this? It a bad thing?

 

had it happen to me, But always use a good fuel cleaner every 5 tanks or so such "seafoam" our cars are horrible for building up carbon and this helps the deterrence of formation of that.
