I haven't tried that yet. I figure it is either fuel related or air related. When I do start it and it stumbles and barley runs I can take my finger under the AFM and push the door open and the idles comes up and smooths out. Is there anyway this can be related to the TPS? I wondered if it was bad and not signaling the AFM to open properly.
When it barely runs it feels like it is flooded. As for the boot to the throttle body I have a brand new one. Also mine is a 5-speed and does not have an ECT
Last week when it was hot I unplugged the cold start injector and the cold start thermal switch. It still didn't start and the check engine light came on.Shouldn't unplugging both of those completely prevent the cold start injector from firing? I contemplated pulling the cold start injector out to see if fuel would come out when hot but figured if it is not plugged in there should be no way of it firing.
.... I probably need to get my multimeter out and start testing all the sensors.
@sirdeuceI previously replaced the rubber intake boot at the throttle body. I also carefully looked for any kind of cracks in the plastic tubing between the throttle body and the AFM and did not find any.Today I did a basic compression test and the numbers were respectable:Cylinder 1Dry 165Wet 175Cylinder 2Dry 175Wet 185Cylinder 3Dry 180Wet 190Cylinder 4Dry 178Wet 188I haven't had a chance to do a leak down test yet as I don't have the equipment to do it. When I have some free time I will take it to my friends shop and do it there.
@GnarlsSorry Gnarls. I haven't had time to work on the 4Runner lately. I had a major dental problem last week that was partially fixed and then the dentist left me hanging due to the Covid-19 stuff. I have been in major pain and they closed their office and won't even see me on an emergency basis. Might be another week or two before I work on it some more. Hope your doing well and stay safe! Talk to you soon.
