When I bought my car it had a screenless MAF on it. Currently I have a small issue with my idle. Periodically the idle will go up to 1500 and down to 400 rpm, and repeat until I give the car some gas. This problem does not occur often, but I wonder if it could be related to the MAF. So, would it be beneficial to buy a new MAF with a screen, or possibly buy a SLP 85mm MAF? They cost about the same. Also, if I added the screened MAF would I lose any power/torque?

That's a tuning issue, you do have H/C afterall. Mine does the same thing, and it's got a bone stock MAF. You could benefit by swapping to an 85mm unit, but I'd suggest a GM 85mm unit, then having it tuned for it. Don't expect to gain a ton of power though, if any, especially over a screenless stocker at your power level. Tuner can also look at the idle hunting problem.

mine used to do it every now and then.

I turned the idle screw up 15 degrees at a time till it quit. Mine would mostly do it when the weather changed.

I have a cam and bolt on car.

all the screen is there for is to straighten out the airflow from intakes that come in at an angle. the screen in f-body maf's are worthless. i've had no issues with mine since taking it out. i do, on the other hand, have the same idle problem you have. came after the h/c install. i'm pretty sure it's from the mail order tune. i hope to straighten it out with the dyno tune

screen has nothing to do with it
