missfire?

I think i may have a missfire. how do i check for it?

Smell your exhaust and see if its rich??? But honestly, you need to be much more descriptive to get better answers... Also, check the condition and color of your spark plug... But I bet you either have a bad fuel pump, bad spark plugs (or incorrect gap for your boost, or incorrect plugs), or the famous bad spark plug wires (let her idle at night, look under the hood for the purple light show)

What makes you think you have a misfire?

 

[eagelfan92]

Low irregular idle, stuttering. Im pretty sure its fuel pump going bad. Im running lean. brand new NGK spark plugs gaped at .030 and brand new plug wires. and brand new fuel filiter

and no CEL

So, did you do a boost leak test?

Anything that deals with airflow (idle in your case) do a boost leak test.
