Just did a long overdue manifold swap and while at it replaced the old
water pump, alternator, and radiator. Runs like a dream and for the
first time since I bought it new I think, there are no warning lights on
Only one slight problem. Idle speed. In neutral its fine. Drop it
into gear and the idle drops so low it wants to die. Looks like the
idle is preset with a loctighted screw on the throttle body that has no
slots for adjustment by screwdriver.
What am I missing? TIA
