hey guys,
everything is back together. The car starts, but makes a loud screeching noise at idle and the car idles at 3000rpm. I'm gonna try a ecu reset, but can the screeching noise from a bad belt? the belt i have now is oem and looks ok. But some people have said it can still be bad while looking good.
Would a bad belt explain my 3000rpm idle?

i was messing around with ignition wires past few weeks. they definitely don't cause higher rpm.
i would think it's an issue between your throttle position sensor and throttle body controller. some where in between there's a short. I would check the wire for the throttle body. make sure it's properly connected.

yes i was referring to the ignition wires. i've heard many members have a high or rough idle and it was because of loose wires. make sure you here that "pop" when you put them back in. its hard for some of them in the back.

Had a smaller issue, It was a vacuum leak, I forgot to hook up one of the vacuum lines to the PCR Valves so it would idle very high at idle. Check your lines. Not sure about the noise from the S/C, are you sure its from the belt of the s/c it self?

where is this metallic screeching sound coming from? a certain point on the belt loop at a certain pulley? or is it coming from within ur supercharger?

hmmm well the only hose that i didnt have one was the driver side crankcase ventiliation hose. i fixed it with one of those hose menders, you think its still linking from that hose? i guess i'll double check the hoses again.

well i replaced all my idle pulleys. i know my tensioner pulley is going bad but it was never been that loud. Its usually loud during the cold start then the sound goes away. i'm not too sure if its coming from the belt or sc charger. i might just change the belt since i have a extra one anyways.

TemjinX2 - I have to agree with OverDrive. It's a vacuum leak.
Get a piece of hose and play Doctor with the car; try to diagnose where the noise is coming from. Since the C3P unit is not the same dims as the OEM you might have a leak by the surge tanks or by any of the sensors on the IC.
The loud noise and the rpm at 3K explains this as the ECU is not reading the correct delta X across the system. If you drive it or gas it, you are more than like going to get a CEL code. P0105 is very common since it gets trigger when the MAP is out of range.
A couple of questions that can help you get to the source...
1) When you gas the car, does the chirping sound goes away?
2) Did you use phenolic spacers at the surge tanks?
3) How did you install the MAP and IAT sensors?

yeah i installed phenolic spacers with the surge tanks. i'll try uninstalling the spacers.
The map and the IAT sensors bolted up to there oem locations.

The MAP sensor is where your problem is... it appears it "bolts up" fine but in reality, the o-ring on the sensor does not sit flush (or tight enough) at the surface of the IC. You need plenty of gasket maker and create your own gasket in those 3 holes (by the MAP sensor) in order to make it work.
It's a PIA since you have to take everything out again but it's more than likely your solution.

You need to make sure the surge tanks sit properly in the back. Adjust the rubber hose that connects the Y-pipe of the IC.

just to give an update..i think the metal screeching sound and the vaccum leak were two separate issues.
i replaced the tensioner idle pulley and the screeching sound went away.
I decided to take everyone's advice. i reinstalled the throttle body, map sensor, y splitter. I think it was a combination of the throttle body and loose map sensor.
I would like to thank splinter for all his help and for convincing me not to give up and everyone else that gave me great input.
Anyways the cars running strong...i'm pretty psyched. i just need to drive it around a bit and make sure the intercooler is fully bled.
