i think it was p-0174? anyway the description was the car is running to lean. I am wondering what would cause this..

A couple days ago i posted this:

I did a little research on this and found some things that may cause the car to idle very low and stall like a vacuum leak or iac needing to be cleaned. I am curious if this would cause the cel to come on?

Here is my situation:

for a couple days it would idle very irratically, bogging down to 250 - 500 rpm then it would shoot up to 2000. a couple days later it started stalling out when it would bog way down. Now it just idles really low like between 400 - 500 rpm and doesnt stall out or rev way up on its own. The cel has been on since the first time it stalled out.

Its a 2000 2.5L with about 60,000 mi. btw

what do you guys think?





I am in the process of cleaning the MAF and IAC right now but i just thought i would try to get some feedback on that code since i didnt know it on the previous post. thanks!
