I have a 1992 pickup with a 22re in the afternnoon only my truck will start cutting out really bad, back fire and will cut off if I idle it does not do it in the mornings for some reason

Check your plugs, wires and distributor.

Here's the things I would check: Compression check, clean EGR, check MAF, change plugs, replace ECT, check for vacuum leaks, check grounds, mist down plug wires and coil with a water bottle to check for spark leaks. Here is a video on another area to inspect.............. https://www.youtube.com/watch?v=czOG-4XdxOQ One other component known to give trouble is the IAC which is located under the intake. I would replace that last. It's the most difficult part to replace out of all the listed above parts. Keep us posted on your findings.....

Those guys both can be trusted on their advice.
