On some makes and models, they had some much trouble with the maf senors, they used a different prom or something and switched to speed density system, map sensor, no maf.

Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. You can call and ask? At least maybe you could rule out the fuel issue? If the problem is temp related, maybe cts? I don't like to throw parts at a vehicle.
