K so I have a 93 Chevy Ext. Cab k1500 with a 5.7 TBI, Auto trans. I'm having issues with the motor idling pretty high, the trans jumps into gear with I shift into Drive, and I have to rev my truck up for it to shift up? Any ideas what to look at first. Thanks in advance for all your help. Just had a tune up plugs, wires, cap, rotor, and about a month ago a new ignition module (in distributor). Was driving just fine then lone and behold **** lol. So if anyone has any ideas, I've read alot of threads and post, sounds like people try alot of things to no avail so I figured I'll ask first. Thanks again everyone!
