Lumpy Runnin'

[Mr Mike]

This problem was occuring before the timing belt install fyi

The car (02 wrx) is idleing at around 500 rpm, or just below actually. It has some hickup/loss of GO!!! just before 3000, like a flat spot in the power band. Idle is lumpy, as if I were running low octane, but I am getting no miss fire warning from the cel.

I am running a K&N filter and the plugs are a year old +, So i am leaning toward bad plugs and a dirty mass air flow sensor....

I have no real question here, just picking brains... or what ever you may have in place of a brain LOL LOL LOL

Vac leak?

 

[Mr Mike]

CEL MIL, whatever you kids call it these days

Check Engine Light / Malfunction Indicator Light

MILF?

No prob, I'll check one out reeeeeal good.

 

[Mr Mike]

LOL CEL is on yes, but due to bank 2 O2 sensor below tolerance (open exhaust). that's the only code on there though, i check it every week just keep tabs on things.

 

[Mr Mike]

Malfunction Indicator Light ;D

HA HA HA HA HA.... I wonder who thought that one up.... the light on the dash says CHECK ENGINE so I have always called it a ......... check engine light... huh imagine that.....

wouldnt a light and an indicator be the same thing??? I could see Check Engine Indicator..... or Engine Malfunction light perhapse

sorry I would beat this up any more

Subaru term, used all over the manual....

 

[Mr Mike]

ahhhh some thing lost in translation I bet

.

Either way I'm gonna clean the maf sensor and check for vac leaks this weekend, maybe reset the comp too, a can of dry gas wouldnt hurt either. How do these things do with injection cleaner???

 

[Mr Mike]

MAF was filthy.... I cleaned that up and it brought the idle back up to where is should be, smoothed things out a bit too.

I still say I could be better though.
