Turn car off... Now a weird sputter.
I have a 2000 civic si with a sc50, rc 550's (new), and AEM(used). It has been tuned and was running great for over 1 year.
Last week i took the car out. Got to my destination turned the car off. Came back after a 1/2 hour. Car starts fine, begin driving, my car starts to sputter. In idle and in all gears. I look at my zietronix and my a/f ratios are very lean. So i drive very carefully home, being sure not to boost. I ceck all the wiring to my AEM and wideband nothing looks wrong. I am so confused.
Could this be a fuel issue? I have fuel pressure (pump priming). Could it be the injectors or my fuel filter?
Could it be any other random things?

Re: Turn car off... Now a weird sputter. (ORcivicsi)
Do the obvious .. Change fuel filter, maybe look into a new pump if you have a walboro they have been known to take a dive for no reason.
Also did you ever check your plugs for detenation??
Plus not to be a dick but its a honda with a turbo they ALL go one way or another. I have been through the stock motor phase and I know haha. So do a compression test and leak down if you can when you check the plugs out.
