Me again with what I hope is the final issue with the engine. I have noticed that when starting cold the engine will start and then slowly die out within 5 seconds. If I feather the throttle a little for about a 30 seconds it will not stall when I release the pedal and the RPMs will slowly rise to hot idle RPMs as the engine warms up. But my cold idle is 500 rpm or lower, while my hot idle is perfectly on spec at 800 rpm ± 25. I suspected the AAV but it appears that it is open when cold and shut when hot. The AAV is only open 40-50 percent when cold though. The mixture is also a little richer like its supposed to be. I also checked the throttle body and it is dead on 0.002". I am kind of stumped, The only thing I am not sure of is when I probed the plug on the AAV I found that the plugs have continuity (connected together) when cold is this right?
Any ideas would be welcome. the problem isn’t bad it’s just annoying having to do manual fast idle with your foot.
