If the MAF sensor is not reading right will that affect the idle at all?

 

Sure can, especially at lower frequencies (airflow) such as that at idle. It has especially been a problem with CAI's. The oil used on the filter tends to coat the MAF wires, desensitizing them. It's not a bad idea to remove the MAF and carefully clean the elements on it with non-residue electronics cleaner.... be careful with 'em though

Of course there are many other things that can affect idle

 

Thanks. I am getting a code for it. I did clean it but it did not help. I am still getting a choppy idle and I believe thats the culprit.

 

As with all suspected bad sensors, make sure to inspect the wiring thoroughly. If you've got another f-body/'Vette enthusiast around try swapping MAF's. If it gets real bad you can simply unplug the MAF and the car will default to speed density mode.

 

I unplugged it and the coolant fans went on when I started the car and it idled pretty rough.
