Just started to cut in and out, feels like it will stop running then it catches on again. I nursed it home for about 5 miles and it did stall once. I started it up after about an hour and it was ok for alittle while then started cutting in and out. Could it be computer/mass air flow/relays?

This can be a fuel problem or a electrical problem. You will need to take to have the codes checked at the parts store and while you are the rent a fuel pressure gauge. Then ck. The fuel pressure when acting up. Then come back we can help u.

Yep this can be many things included the MAF sensor, I would run the codes which this guide can help with and if a code comes up for the MAF I would replace it.

Here is the MAF sensor location. Check out the images (below). Please let us know what happens.
