Warm day = low power

[acsilver877]

Hello everyone. I have a 1993 pickup 22re. It runs fine on cooler days but in the summer when the mercury reaches about 95 F and higher, the engine loses power. Acceleration with the a/c compressor running is very weak.

The plugs and distributor have been replaced. The air intake filter is new. The truck has been pretty well maintained, but it has about 160,000 miles on it.
