So, yesterday, I went to start my car, and the weirdest thing happened, it tried to stall and die on me, at a cold start, I wasn't sure why it kept trying to do this. I turned it off and started it again, and it seamed ok, so then I tried driving it, it drove ok but the idle while i'm moving is everywhere, if I take it out of gear sometimes it will idle at like 3000 rpms for no reason till I stop than it goes down to about 1100. The most annoying problem though is everytime I take my foot comepletly off the gas especially when down shifting, it JERKS really hard, makes it feel like I'm learning to drive a stick all over again, the rpms stay the same but the car jerks badly, only when given no throttle, it's ok when I give it a little gas. Thanks for any advice and help u guys can offer. A little info. Using stock p13, obd1 h22a, no cels, timing good, I do have clicking valves though, need to do a valve adjustment.
