93 22re, fresh rebuild
The engine will be running fine idling like gold and smooth power when on gas, then it will have a spuddering fit that i can rev threw and lasts a minute. It can start sputtering at idle, acceleration, or engine deceleration.
I took it to toyota and the told me to replace the ignitor assembly, coil, wires, cap and rotor. so i did. The spuddering continues and i have no clue what it could be.
Any help would by greatly appreciated

Whens the last time you changed the fuel filter?

I originally thought it was the fuel filter, but the problem seems to get worse when its raining or the humidity is high. This is why i think it might be electrical. Toyota told me to replace the ignition system, so i did. Could it be Injectors?

Fuel filter has been replaced, problem is still happening. When it is sputtering out i can tap the gas and keep it going. If i go to far into the throttle, or keep the gas depressed the engine will bog out and want to die. I have no clue WTF is wrong, i have replaced the fuel filter, ignition coil and assembly, distributor cap and rotor, and the wires. I have no clue what this could be  |

I'm still thinking fuel related... maybe intermittant injector failure causing you to lean out? (thats when you get the sputtering) that would explain why it stops when you feather the pedal a bit...
also maybe it could be a vacuume leak?
I'm kind ashooting from the hip, but I hate these intermittant problems, they're a mother F-er to troubleshoot

Check your throttle position sensor. I had a similar problem with my 4runner.

I know its been awhile since this was posted but I am having a similar problem with my 88 4runner 22re and was wondering what you did to fix PIA problem?
I noticed that the pulsation dampener on the fuel rail was leaking I tightend it and it seemed to stop leaking but it seems to still be bad, but I have no idea if that is the problem or not.
If you could my email is mopower13@comcast.net thanks for any info.

I second checking the TPS. When I put the EFI on my 87 the truck would idle but when I gave it any throttle it would run rough and sputter. Turns out when I put the TPS on the throttle body, I didn't have it lined up right.

The problem with my truck was with the sensors. I had a bad engine coolant temperature sensor, making the engine run rich, and a bad 02 sensor, making it want to run lean. So the conflicting engine codes were making the whole fuel air mixture messed up.
If i were you, i would look into sensors. Everyone always says TPS but i have had alot of problems like this and it has never been the TPS yet.
