Seems like the problem wont go away upon cold start this happens it starts yet idles low i gotta push the gas to at least 2k for about 35 seconds
(sorry for text message ringtone)  and it begins dropping low to about 300 and my car begins to rattle ALOT.  but once the engine is all warmed up it idles here and everything goes back to normal.(same vid posted from previous post)  this coldstart is becoming an issue now any ideas guys? --------------------  |

During a cold start, two things need to happen.
1. The idle control valve needs to open pretty much all the way. 2. The car needs more fuel. If you replaced the idle control valve, check the tubing going to it to make sure it is in no way kinked. If the problem is with your car not getting enough fuel then either check for vac leaks between the MAF and the engine. Since the car is not MAP based, any little leak could make the ecu inject less fuel. If that checks out, inspect the coolant temp sensor and wiring, since that is what the ecu references to determine that a cold start is happening. -------------------- 15PSI - 30MPG - Megasquirt Tuned
