If its idleing wierd you should check ur IAC to make sure its opperating corectly? could be somethin simple. What temp thermostat did u put it?
180* t-stat, it is actually getting better the more i drive but the initial start up sucks, cold start it dies almost imidiately after i turn it on then if i hold throttle to 1500rpms for about 1 minutes i holds perfect idles and runs great. the t stat isnt messing up anymore either....weird? i dunno this car is funked up sometimes. oh well ill figure it out, i think i know whats wrong with it, except for the intial start up...ideas? when its warm it starts fine and hold idle....only when its cold does it have problems

How much have your driven it since the problem started, and if you have, has it gotten better? You disconnected the elctrical power, right? Maybe the computer needs to relearn?
