Rough idle, check engine light
 

Ok, maybe not rough idle, but my car runs wierd when it's idling. The rpm's will hold between 1000-1500 and every so often (i'd say 3-5 seconds) the rpms dip for just a second and then come back up to the idle speed.

It's like the computer's trying to lower the idle, but can't do it or something.
Any ideas what the problem is?

Also, there's a check engine light, could this be related to the idle issue?

Check the IAC (Idle Air Control) or run a diagnostic code test on it.

i think i'm gonna take it in...
and just tell them to fix it.
i've gotta have my ride goin by this spring!!!!

i'm tired of sitting and waiting for it to be fixed...
tho i'm slow at fixing it.

Alright. Let me know what they find out.

run the code

what do i need in order to run the code?
should i take it into a shop to do that?

find a buddy with a red brick (code reader) or i think some places do that for like 20 bucks

get a haynes manual and a paper clip, or spend about 10 bucks on a reader at any parts store

10 dollars??? what kind of reader is this? Ive always only known the expensive ones (snap on)

Paper clip is the quickest and cheapest way to do it. Thats what i always used on my 3rd gen.

obd1 can use a cheapy the snap on one is the same as the lower priced ones that sell for about $175 at most parts stores

yeah at my work, we have a couple of them. The snap-on one was a lot more than 175! i think it was well over a $1000!

snap on = way over priced the tech1 that the dealership I worked at used was only $200, a tech2 runs around $300 off the trucks, or about $200 through the supplier that makes them

yeah snap-on is really overpriced but thats the brand of choice for my field. Everyone will give you a "lifetime warranty" but that doesnt help you much when your on a job fixing equipment so they can continue working and then a tool breaks! I own a lot of snap-on tools....thier worth the money!

I own one snap on tool (and it's broken) I prefer mac or their parent company stanley (take a stanley to any wal-mart and they replace it no questions asked even when it shows abuse)mac has mailed me repalcements for screwdrivers that I used as prybars
