Idling problems :(
Hi all. This is my first post on the forum.
I changed my power steering pump and my valve cover gaskets. In the process of changing the gaskets, i had to take out my intake. Which meant unplugging the IAC and the TPs sensors. Well, i got done two days later, but the car idles very low. The RPM doesn't go above 2000, and it shakes a lot when i step on gas sometimes. I went some where and the computer gave me four codes.
P0100- Mass or Volume flow Circuit.
P0308 Cylinder 8 misfire
P0110 - Intake air temperature circuit.
P0120- Throttle Pedal Position sensor switch A.
My main concern is the 4th one. Can someone show me how to adjust that?
I have retightened and checked the spark plug and wires on Cylinder # 8.
I have plugged and unplugged the IAC and TPS plugs, but still the same problem.
Can anyone help, please.

Welome and great job on the detail of your post! I think the year may help some too. It sucks to do that much work and then have these issues. I would recheck all my steps again for sure, be sure and clean your connections with the proper cleaner - (some connections require a protectant lube - looks like lithium grease) if you have a meter you can check the resistance on your sensors to be sure they are within spec. your plug wire needs to be checked as well for damage, even a small pinch can cause grief.
I would hope any of these sensors arent damaged, if you did a careful job they should be fine.
good luck and Enjoy the ride!
Im sure the P0120 code can be assisted with the Search option as well -

Adjustment procedure here

Recheck you have plugged the MAF back in and recheck all vacuum hoses especially the ones from the valve covers to the throttle body.
Pulling off the spark plug wires especially if they are the original ones can damage them which may explain #8 misfiring.
