My 01 Altima spudders and dies

[ccmdude]

My car started doing this after I filled it up at a gas station. I was thinking it was just bad gas so I put that stuff in the tank to knock out the water. However, I haven't used up that tank yet but it still does it, loses power (rpm gadge drips and comes back up and the check engine light flashes real quick) and sometimes it shuts up, but it cranks back up. I was wondering if it sounds like bad gas to you guys or do you think it's the air intake manifold gasik, I heard those are prone to go. Thanks

likely the intake gasket. if you spray some carb cleaner or brake cleaner near the #4 intake runner (near the throttle chamber) and it changes the idle, then it is the intake gasket.

...if not, then you need to replace the plugs.
