When I start my car when it's cold, it idles nicely at about 750 rpms. I let it warm up 5 mins and start driving. As soon as I come to a stop, the idle is now at 1,000-1,100 rpms and any time I stop after that, that's where it idles. If I drive it hard then come to a stop, the idle surges from 500-1,100 rpms for about 10-15 seconds and then it evens out back at 1,000 rpms. I just got the car 6 months ago and hardly drive it and haven't done any maintenence... I'm wondering what I could do to fix the idle. I was thinking maybe its pcv valve or iac valve...That's just a guess though. Could it also be a vacuum leak? I know there is a surging idle thread but I was just wondering if someone could chime in that has heard these exact symptoms and tell me what they think.
Now, kind of unrelated. I do drive the car hard and today while on the highway a new Charger RT wanted to play and I was going about 70 mph and dropped it to 3rd and floored it until redline. So once I was going way too fast, I tried to shift to 5th but it didn't want to shift. The shifting has been a little notchy since I bought the car but now it seems I have accelerated the problem. When I came to a stop I had a hell of a time getting it back into 1st gear. And now the shifting is very notchy and the faster I drive and shift the harder it is to do so... I also noticed that now when I come to a stop, at idle the car vibrates pretty noticeably...which worries me. What does this sound like? Could it be as simple as a worn clutch that finally gave? I haven't checked the clutch or tranny fluid, I guess that would be the first thing to do huh?
