Running like sh*t...
 

the idle wont stay constant moves up and down between 700-900... and its miss firing...any ideas it has to be a simple solution?

A few details about what you're running would help a great deal

lol my bad... koyo radi, front mount.... no cats down pipe, power FC, stock twins

Start with the plugs.

plugs/wires...how is it under acceleration?

Check the boost sensor.

+ 1 for plugs and plug wires (depending on how old they are). also i'd inspect/de-gunk the ISC if you're still rocking it

check to make sure your MAP sensor is plug in

what he said ^^^

plugs and wires have like 2000miles on them brand new
