KA having stuttering issues

[Wbarnes13]

Anyone in the West Palm area of South Florida have a MAF I can use to diagnose a problem? I have a 1995 240sx with a stock KA24DE in it. Lately it's been having some stuttering issues around 3K to 5K it seems like it runs out of gas and has no power whatsoever. Every now and then when this happens I'll have to pull over and it will die out then start right back up. I'm thinking my MAF is shot. I checked my grounds the one on the intake mani sides looks fine and I'm told there is another one on the back of the head on the exhaust side that one looks like it's not even there. I have changed the plugs and wires, cleaned the MAF, and IACV. Any help is much appreciated thank you.

Today I took my throttle body and gave it a good cleaning. It seemed to have helped some, prior to cleaning the throttle body the car idled a little high at about 1k to 1,100 now it's idling at about 700-750 so far it hasn't stuttered or stalled. I'm going to drive it a little bit more and see what happens.
