OK, you all might remember me from an old thread with the black smoke hard start problem. I thought I should start a new one.... as some of what I wrote in that last post was misleading and or has changed. See... the 4 runner was my wife's and I finally gave up and bought her a new Subaru... now I'm driving the 4 runner and since I'm driving it every day I've gotten a better feel for the problem she was having.
Here goes:
1994 4runner V6, I've tested the computer codes and there are none. I've tested the pins on the VAFM and they are all to spec.
In the morning after being cold all night it starts fairly well and much better since I found that hole in the air intake hose between the VAFM and the engine. The remote start almost always works now from about -10 and up.
After I drive it and warm it up well.. maybe running it more than 20 minutes I can turn it off and immediately restart it and it starts ok again.... not great but well.
The problem is when I drive it somewhere and park it for a couple hours and come back to it. The remote start never works, I can crank it and crank it for say 30 seconds without touching the gas pedal and it will start or I can touch the gas pedal some to get it to start quicker but this is where the black smoke comes into play... presumably because I'm making it very rich by touching the gas.
Early on SB5walker said that he thought the tps or vafm since it was bad from the start but now that we/I know it's not nearly as bad at the start as it is during the day after it has sat in some parking lot for more than an hour do you think it could be more the ECT? Where would I find the specs of the ECT in the manual?
OK guys thanks for all the help.
