HELP!!

I have a 98 4runner limited and I am having the exact same hesitation
you are talking about. I can rev the engine from the engine compartment
and there is almost a sec delay before the engine revs. Also there are
times during acceleration the engine runs smooth and then sometimes it
sputters. I am receiving trouble codes P-100(MAF sensor error circuit)
P-110(IAT sensor error circuit) and some random cylinder misfire codes.
The
cylinder misfire codes are most likely to be caused by the MAF or IAT
malfunctioning. I have changed and checked all wires and sparkplugs.
Since the error codes say sensor circuit there is most likely just a
bad wire somewhere???? I bought a MAF from a salvage yard(pick a part)
and
that did not solve the problem. Those *******s are expensive. Any
Advice????
