msd coil pack
and
dinan intake no silicone hose

and theirs no check engine light and one kno whats up with my car? its really pissing me off

 

Did it just start doing it all of a sudden, or did you recently make any changes to the car?

Also, do you only have the low idle when the air conditioner's on, or with it off as well?

 

I thought this would be about girls...

 

it started happening after i got some parts on

 

I was thinkin' graven images. But then, I'm older than you. Pre-tv, even.

Well, don't keep a secret - what mods/maintenance were you doing right before the problem started?

I would start by check all of the vacuum hoses under the hood to make sure they haven't come loose or developed cracks/splits. A small vacuum leak can cause a low, rough idle - even if it's not bad enough to throw an engine light.

Once you have the engine speed up above idle, does it feel okay?

And dandennis: what parts did you put on just prior to the problem? Inquiring minds want to know.

i may be totally wrong and someone please correct me if i am, but the car will take a ltitle time to adjust to the bolt ons especially the pulley, i dont know from experience for my pulley was on when i got my mini, but i have searched and read many times on the pulley doing that and should pass as the ecu starts to accept the extra air flow and adjusts accordingly

 

unichip, alta 17% sc pully, magnaflow muffla with a lil bit of piping, msd coil pack and dinan intake no silicone hose i put these on with in the last 3 weeks

 

it may even just be the unichip, the a/f ratio for idle may be off

 

The ECU does "adjust" for things like A/F ratio, engine octane, ambient temperature, etcetera, but all of those adjustments are virtually instantaneous and being made continuously as you drive the car. I don't think the ECU does any long-term "learning" or "adapting" to your driving habits or engine modifications.

 

Agreed. The sensors read various engine conditions, the ECU compares them to parameters, changes are made on the fly. No learning curve that I know of.
