Finally got my yota back road worthy.... well i thought. Its a 92 22re efi in a 93 4x4 pickup, aftermarket headers. My problem is that it runs decent cold, but when it warms up it runs like hell. I give it gas on the road in 2nd and it sputters and sounds like its gonna die. No vacuum leaks and throttle positioning sensor is good. Any other ideas would be great, thank you. Also speedo dont work, but i think thats a different problem.

make sure the secndary ignition components are up to snuff (cap rotor wires plugs)

just a 22re

check the timing i got mine set at well a 1/8 in to almost full turn adv BUT she was built to handle this so make sure yours is timed right get a timing light and see where your at

yea... new wires and all that and had a shop tell me the timing was 100% perfect dead on, said they couldnt do it better. Thanks fellas. If anyone has had problems like mine please shed some more light. Im stuck.

If I were you I would check the valve lash. If the adjusting screws were set as the engine was cold it won't work the same when it warms up. They should be set at normal operating temp. so it runs rough when it's cold and then good when it's warm. I'm not a mechanic so I could very well be wrong but it's never a bad idea to check the valve lash.
