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.

so it seems i fixed the problem on my car.

i managed to get another sensor from a junk yard. my original sensor is #89462-20020, with a white harness plug (on the sensor itself, the wiring harness plug is brown) and it says its its a 7k resistor. the new one i found is part number 89462-20030 with a brown plug and it says its a 4k resistor. it came out of some random toyota, but the wiring harness plugs right in. i installed it and the car starts right up on 1st crank. ill have to give it a few more days of cold/hot starts to make sure the lower resistor dosnt cause a problem, but so far it seems to work well. ill report back again in a few days if anything has changed.

the funny thing is, when i took out my old sensor and tested it to the bgb specs, it seems to be totally within spec! maybe the contacts were not making a good connection or something else was going on, because it seems that is was in fact the cause of the problem.
