Idle to high after TPS adjustment.

Hi there.

I've adjusted my TPS to .5 volts, and now my idle won't drop below 1100 RPM. Could someone sed some light on what may possibly be going on here? A little background.

I previously removed my intake manifold to replace the water manifold gaskets, whilst I was under there, I replaced all the vacuum lines and egr related hoses with new ones.

I have double checked all of my connections underneath the intake manifold. Could I have reveresed on of the vacuum lines?

In following with a reversed vacuum line as a tentative diagnosis, could someone provide a diagram that illustrates the correct connection of lines?


Thanks,
-Patrick

Is your throttle cable too tight?

if you cleaned a bunch of junk out of your throttle body while it was off, you may need to pull back on your IAC a bit. I did this to mine, and I had to adjust it. I believe that this is only due to the fact that a previous shop had adjusted it previously to make up for blockage in the throttle body passages (once the junks gone, it flows too much air). I was able to get mine going in an hour by adjusting this. The bad news is, if you end up going this route, you will have one HECK of a time adjusting it while the throttle body is still connected. Be careful when you're doing this though, you should re-start the engine between adjustments. Only adjust it while the engine if off, the sensor tried to stabilize the idle, but seems to "jump" between settings. IE: once I pulled back on the idle IAC a bit too much, the car would attempt to idle at 500rpms and then after being rough for a second, it would automatically dial it up, but would over shoot it to 1000rpm. Good luck!

BTW, the IAC is the box under the throttle body with the large hose coming from it.
