92 3vze bucks when pressing the gas pedal slightly
Hi I've got a 92 toyota pickup with the 3vze and it will run fine but if I just slightly press the gas pedal it will start to miss, when driving it will start bucking. I can completely let off the gas pedal no matter what gear I am in and it doesn't do it and I can also floor it in any gear without it acting up.
I don't get it. Runs great if I put my foot in it but if I'm barely holding the gas pedal, for example trying to hold my speed, it will miss and cause the truck to buck.
Any ideas??? Its really starting to annoy me. Thanks!

Dirty throttle body, bad plug wire/wires, dirty air filter, vacuum leak, maybe a stored code, and that's only a few.
I would download FSM www.ncttora.com/fsm/ as this will help you with diagnosis.

Get some plug wires on there. Mine ran HORRIBLY before I replaced them. Hold them in your hands and flex them around checking them for cracks etc. Even if it's not 100% of your problem, chances are if they're as bad as mine were they are arcing all over the place while you're driving around.... My problem was worse after warmed up when the wires were bad.

ya it could probably use them. ill see about getting some new ones today. it seems like if the plug wires were bad the truck would run crappy ALL the time. like i said, if i put my foot in it , at any time, the truck runs great. very frustrating

Well when my plug wires were shot it was more of a low rpm/off the line thing. At full throttle while moving it was fine.
It is frustrating. I can't wait til I get mine fixed! If I do soon, I'll let you know what it was.

ok so swapped out the plug wires and where you plug the coil wire into the coil, it has a little corrosion inside so i did my best to sand and clean it. put everything back together and if i try real hard i can still get it to buck and jump a little but even now its better than it was, like WAY better. so keep cleaning to connection? would it be worth it to replace the coil?
by the way, thanks for the help guys i really appreciate it
