That's what they do. maybe check carb settings and such.
because that's kind of a big engine
Idle is computer controlled, there is no adjustment screw.
it has a low idle. Can also be a vacuum hose leak.
Reset your injector timing to compensate for the added boost at idle
z idle adjustmentTurn the idle screw - on the intake manifold - clockwise to decrease rpm or counterclockwise to increase idle. You should also look around for a vacuum leak
Aprox 650 rpm in drive.
Any engine advanced (especially one tooth) will start and idle awesome, but run like crap at high RPM. Remember, at higher RPM, the engine will want to "anticipate" a cylinder compression stroke and will want to spark "in advance". However, at idle, igniting the mixture just past (retarded) TDC will prove to offer a very smooth idle.
check the accelerator cable, i had a problem with this, and also had a split in my pedal at the same time
could be: sticking throttle linkage, idle air control malfunction, or in emission system.
A vacuum leak could do that. Did it have a high idle before you changed the throttle body? Any codes?
Try some fuel injector cleaner in the tank.
Yes
