Throttle sticking/hanging
About a month ago I took my TB off and cleaned it up. Not to dirty but still a little gunk behind the throttle blade. Had the car out last night and noticed the throttle sticking/hanging on me. Like if I was cruising at 40 and would put the clutch in the throttle would stick or stay at 2000rpm. Got on interstate and was going 70 put the clutch in and the rpm's went up and hong there. I would have to hit the gas a little and it would then come down to idle. Pedal not sticking and the throttle moves find when i checked it by hang. Any thoughts please??
