Where's the flamethrower?

ok, here's the deal:

one day I was driving around and everything was running perfect. I parked my car at my friends house and went inside for a couple hours. I come back out and the idle jumps way up to like 3000 rpm. I retarded my timing at the dizzy to get my idle to normal but it would backfire real badly.

I got home and reset the timing at 10btdc (spout out) and same thing. The idle would raise wayyyyy up and if I hit the gas peddle the rpms would rise and stay there for a bit. My vacuum gauge was reading 14"-15" which is normal for my car.

Well, I unplugged my IAC (with base timing at 10*) and the car started to idle like normal (maybe a bit lower). So I thought maybe something was wrong with it. I replaced it and same deal.

The only thing I can think of now is that the balancer spun on me...but it looks like it's fine and I have no vibration issues. I thought it was weird that it was fine...then I cut it off....and then it wasn't fine next time I started it.

Any ideas? Sorry about the novel

also, I had another thread with this on it but couldn't find it because every time I tried to go to it, it wouldn't let me for some reason.

already replaced it and it didn't change anything, thanks for the input though.

Holy stored codes batman:

well, I got:

121 - TPS out of spec
122 - Low voltage TPS
124 - above spec TPS
179 - Lean part throttle
185 - Below spec MAF sensor
188 - lambda on left too lean @ part throttle
327 - EVP or something of the like.


ok, the lean code is because of when I was messing with the timing. The code 327 was because I had the IAC unplugged (I think). I don't know what the deal is with the MAF sensor...but I guess I'll clean that up and see what happens, too. It almost seems like a harness came undone or something.

I'm guessing my TPS is all jacked up seeing as how it threw 2 codes.

Any other input on these codes?

Bill302, I think you're right on checking the TPS, haha. I'm gonna do that now. I'm just gonna datalog it and see what it comes out to.

update:

TPS voltage was at 2.020 or something like that.....wayyyyy outta spec.

EDIT: A new TPS later and the car is good to go.

Thanks

yup, everything is fixed now after getting a new one
