cold start time injector switch, first start of the morning is a rough one Options

[brianforster]

so art and i were talking and we both seem to have the same problem, the first start of a morning when its not really cold or not really hot and the car seems to bog out, maybe requiring 2 or 3 cranks and then from then on during the day it fires up first time.

has anyone else ever experienced this with their swap?

art thinks (and i agree) that it is the cold start time injector switch, but that is an 80 dollar replacement from toyota, so if anyone else has had this problem or has any other ideas, id like to hear them.

Doing this really helped me out with the help of Jeff's pic and guide...if you are having some trouble starting up early in the morning, where the car bogs on and off...

1. Remove the whole Throttle body piece from intake manifold

2. try removing the IAc attached to the throttle body, unscrew the four small screws that holds IAC in place..

3. Clean the IAC with some B-12 Carb formula with a Metal small brush to brush off all the black gunk stuck in the small holes in the IAC...since you are doing this, might as well clean your throttle body and intake manifold to your best ability with some of the Chemical (B-12 Carb formula)

4. Let it dry for 10 minutes and attached everything back together...

This should solve problem...better air flow and suction...stronger the car is at recieving a better idling at higher RPM...

*note: if you are unexperience and don't know much and scared to do it (like me)...it will take a while...more than 4 hours of frustration and anger...because of bolts that won't come lose...if that is the case... use a VICE-GRIP TOOL to get the small bolts/nuts out and replace it with M5-.8 nuts/bolts...preferrably the 5mm x 16 should do the trick...found at home depot...$0.75 On the other hand, if you know what to do, less than 15 minutes for everything to work out fine

**I just took my whole throttle piece to a shell mechanic store to have them help me turn the stubborn nuts/bolts off from my IAC connected to the Throttle Body...using their VICE-GRIP TOOL....didn't charge...they just twist it and turned it out for me...

I haven't had the chance to ride it and test it in the mornings...but i will update. REMEMBER, this is just one way to help, if this doesn't help out at all....might be your small THERMOSTATS that's messed up, or some other parts....this took me a while to find the solutions to solve this darn problem...hope it helps you guys...if in doubt, aim me @ chasquare...
