running rough/missing when warmed up
to start off i have an 87 pickup with the 22re, when i start it up cold it runs smooth for a few minutes until it starts to warm up then it starts running rough and misses badly, without giving it gas it wont idle on its own.
i already changed the routine plugs/wires & cap/rotor with no improvement
i have exactly one week to get it running good enough to drive across the state and dont know where to start next

idle speed, timing, etc. are always set with the engine warmed up. take care of that and you'll only have to deal with a truck that won't idle well (maybe) until warmed up.
then you can fix the things that affect cold idle: idle air valve / auxillary air valve, cold start injector timing switch and cold start injector.
get it running well warmed up first then trouble shoot why it won't idle cold.

Maybe I'm being a brickhead, but how does the cold start system affect cold idle? Do you mean under normal operation or in the event there's a malfunction that there's any effect?
