Get this, truck will not idle once put into gear but when in park/neutral idle is up so high the truck jumps into gear hard and then nearly stalls out. Once you hit the gas, even slightly, the truck will take right off until it's time to stop at a light or stop sign, which makes it nearly stall again no matter how warm the engine is(gotta throw it in neutral to stay running). I plugged in the bypass on the diagnostic and the "check engine" light just repeatedly blinks 11 times one right after another, pauses, then blinks 11 times again. Book says code 11 is a ECM but why would the thing drive all day long once the gas is applied? It used to never stall out at a stop but up until a couple days ago it has started to stall, so I cranked up the idle with the air-screw and the throttle-stop screw but it didn't help much, it now surges like crazy. Did moving either one of them mess something else up? This thing has never idled smooth since I bought it but always ran at a stop without shaking me out of the seat, unlike now. Could a fuel pump do this? That's about all that hasn't been replaced on it as of now. Truck has a completely new exhaust from front to back, new plugs/wires, etc and still will not idle good. The "check engine" light doesn't come on except when first started but then goes right out so it seems not to be whipping up any faults, amazing considering the way it runs rough at an idle. This thing is really starting to get annoying, especially with the auto tranny, at least with a stick I could clutch the problem right out of it. Anyone else have a similar problem or is this machine "unique"? Oh yeah, the stock, in-dash temp gauge is bypassed and a mechanical aftermarket was installed, weird thing is the truck only runs at 160 degrees but when warming up it can hit 220 but then drop like a rock and never climb past 165-170 no matter how hard I beat on it, which has been a lot lately:) Is this a normal Toyota problem too?? It's been a good truck other than this, just keeps on going...even when "broken"....180,000 miles and counting!
