hey guys, I have a 1995 chevy c1500 with the 4.3 V6. this truck is 2 wheel drive as you know. now it has around 200,000 miles on it. just last week i finished the engine swap. but before the swap and after I have been having troubles with the Throttle. When I shift from 4th to 5th it sometimes idles down 1,000rpms less than where ever i disengaged 4th gear often sounding like 5th gear gets bogged down and making me look like i can drive stick. so im wondering if anyone else has any trouble with throttle issues and how i might go about solving this one. another thing the truck does is it will idle anywhere from 900-1,000rpm. and i know that its too high. when i got the truck it idled at 600 or so.
please guys i need your help!
thanks,
