I was wondering if anyone could help with this problem. Good luck with understanding what im about to write. I know its gonna be a little tough to diagnose bc explaining it is gonna be difficult, but here it goes. If im driving down the road in my 88 22re and im pretty much cruisin about 55 mph or so. I have my foot just pretty much laying on the gas pedal without really pressing it, ive noticed the problem. You know how if you go really slow and you just hit the gas and let off over and over, the truck kinda just jumps? Well mine is doing this at 55 mph. If I hold the gas down a little it wont do it, but it seems like its doing it when i have just a little pressure on the gas pedal. This is horrible!( bad enough that everyone riding in it notices it on the road). I know the description is long and not clear but any help would be great.

Check the condition of the throttle cable first.

Always do an initial visual check when a problem arises; it's a basic maintenance rule.

Sounds like throttle position switch... Not sure on '88 22RE engine, maybe someone can confirm or say following doesn't apply to that vintage.. but it is as described below on the same era 88 Camry 4 banger...

Under coasting or "trailing throttle" conditions as it is called, (i.e. the truck is coasting and spinning the engine at higher than idle rpm, and the accelerator is all the way off), the engine is in what is called "fuel cut" mode, the fuel injection is cut totally off to the engine... none injected at all (otherwise this is a very high emissions and waste of gas mode)..

When correctly adjusted, as you lean into the accelerator very slightly, fuel begins to be supplied to the engine again, but at very small amount based on accelerator position and at the point of a very small amount of throttle opening, hence, a smooth transition.

If the TPS is missadjusted (and fuel cut mode is still active as you get into a bit of throttle opening) it's going from no fuel feed to a fairly significant amount of fuel feed, hence the jumping/jerking in the the engine. Some people think the external throttle body/butterfly screw/stop adjustment is the correct way to change idle speed and futz with it.. Idle speed is controlled by the ECU and the IAC valve. Changing this screw setting will totally screw up the TPS settings and cause the above, and other problems.

Also, the Idle Air Control valve control by the ECU is not activated until the idle stop switch in the TPS goes closed. So wrong TPS adjustment can cause lots of flaky things to happen. Wear on the throttle body shaft, eventually messes up the TPS adjustment and makes the adjustment even more touchy..

The TPS adjustment on my wife's '88 Camry, 4 banger, 5 speed has always been very touchy to not get the jump as you mention.
