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.

Thanks Art. I got the water temp sensor (green harness plug) and the cold start injector time switch (brown harness plug) out. How much coolant is supposed to leak out? After I took the cold start sensor out, almost a cup has leaked out already. Is that normal? Can you also update me on how your 4k resistor is working? Have you had any problems with the reduced resistance?


Does anyone have any input on the "hook" thing? You can see the bolt that is holding it to the engine in the bottom left of the pic. At first I thought it was a support for when you pull the engine, but it seems a bit too thin/flimsy for that.

4k resistor? you mean the difference in resistance ratings of the two sensors? it works ok. car starts right up on first crank, ever time. but i can kind of tell that its not 110% what you would get from the proper sensor. but thats just me being picky.
