Ah! Car won't idle! Help! Revs to 1.7k and dies??

Alright, at one point in time, the car was throwing DTCs for MAP and MAF. Which I understood could also mean my Crank Position Sensor was bad too. Replaced CPS and MAP. It's not throwing any codes now.

The way it behaves: you start it, it revs to around 1.7k, then just DIES. New plugs, new fuel pump, I have spark and fuel. No DTCs. Any ideas? I'm at a loss for words here. I tried to switch out my MAF with one from a buddies 8, still no luck. input gentleman?

It's possible it could be the ISC.

I would say ISC/IAC first. I just went through this with my car and it ended up being that. Does it stay running if you unplug the MAF? Then plug the MAF back in and see if it stays running if you unplug the ISC/IAC. If it stays running then it is probably the ISC and someone just posted that they are the same as a Dodge part and only $108 new.

ISC/IAC, or Vacuum/Boost Leak.

It's actually harder to start with the MAF off. I switched it with my buddies MAF, and still nothing.

I'll check out the ISC.

Oh, I don't suppose you guys happen to know the part number for the whole accessory belt tensioner assembly? The one that's right next to the oil filter? I snapped it the other day. Gotta love salty German winters. :/

If you can comfirm that the dodge one fits and provide a part number, I'm sure everyone could benefit from that information here.
