Throttle Sticking
Hey all - first timer here, LONG time lurker. Been hunting the Challenger since I saw the concept when it first was driving around the country - and I was hooked. Back at the end of May I finally couldn't take any more punishment and got an 09 R/T with the 6 speed. I'm still in awe everytime I see it parked or in the garage, but I've recently ran into the issue that I've read about, hoped I wouldn't get, but now have experienced.
Driving away from lunch in ~90 degree weather last week, my throttle was sticking out of first around 2500 rpm, and wouldn't come down unless I let out the clutch a little, then back to the floor. This happened multiple times on my way back to work, and was REALLY annoying at some 4-way stops. I had the AC on, and as dumb as it sounds I've only seen it happen so far when the AC has been on, but I replicated it again when at my parking lot back at work. It stuck at a solid 2500 rpm in neutral even, and again wouldn't come out of it until I depressed the clutch (not to the point where it started grabbing), then pressed it down again. I was pretty nervous and ticked off, but glad it didn't get me in any trouble.
The next day was about the same temp, and out of my garage to my destination it caused no issues, but after it was sitting in the sun for a few hours there and I came out to run an errand (with the AC on again) - it pegged again. Each time I shut off the air it "seemed" better, but that didn't make a lot of sense to me. I'll tell you right off the bat, I'm not a gearhead - so cut me some slack if I'm stating anything obvious to you guys. But I thought from my reading this was caused by two different sensors that might be faulty - wasn't aware that this was in any way connected to the AC, but it seems to always happen when it's on.
I have an appointment tomorrow morning with the local dealership to get it serviced, but with the weather the way it is (cooler), I'm not sure he's going to see the issue. I have the time/date when these events happened, so they should be able to see what was going on (computer logs these events correct?) - but is there anything specifically I can tell them to assist in getting this fixed? If they can't reproduce this am I out of luck until I find a hot day where they're not busy and can see it?
Just worried, I've been fortunate that it's never been so bad as to get stuck in WOT like I've seen some other have happen, and I've been able to control it when it does - but I'm nervous that it could cause problems in the future. I've done zero mods to it, and it's only got a little over 1k miles on it. Was hoping some of you have been where I am and could give some advice? Thanks!!!
