Running Rich

[paramnesia]

so my supra is running really rich. me and my buddy where taking a look at it and the only thing i could see or think of was a bit of a pinched fuel line.

but could anyone give me so more ideas on what it could be?

the other thing i notice was a bit of a miss fire. i mean like the most minimal miss fire could have something to do with it?

if anyone could give me some insite to what it could be. that would be awesome!!

Thanks

i doubt a fuel line is kinked since we have hardlines. check your codes and your sparkplugs then get back to us

Think about that for a second, what is the o2 sensor for?

Ok i know the o2 sensor regulates the air/fuel mixture kinda right?

lol

Something else to throw a code... ? :sarcasm:

OP:
have you checked for a boost leak? Checked timing?

When the ecu is in closed loop(Engine warm, among a few other things I belive.), very much so.. Look into it! Plus it'll save you some serious dollars on fuel.
