Recently my engine has started to stutter if I rev it quickly in neutral. It also idles rough. I am guessing something involving fuel or ignition. I run seafoam through the fuel every few months and did just a few days ago. Cap, rotor, and plugs were replaced a few months ago.

 

seems like i answer all posts this way: o2 sensors! haha... has it been on a code reader?

 

No CEL. That is an idea though, considering its also burning more gas than usual.

 

ah! there might still be a code stored in there that hasnt tripped the CEL

yes more gas consumption is an indicator of o2's!

 

ah good answer o2 man
U rock
