I have not been able to check the codes. It just runs really bad, no power missing and the etc warning is on.

Doesn't sound right. Try putting the stock unit back in,... see if it runs okay.

These aren't rocket science to install, so something got jacked up somewhere..

You didn't put alot of oil on the filter did you? The Himi tech at the dealership I go to says that oil can cause all kind of problems with throotle bodies.

What do you mean by "it runs really bad".

Is there an acceleration issue?
Is it hard shifting/no shifting correctly?
Are you getting a check engine light?

Another thought would be to clean the connectors for the intake temp sensor.

In the instructions, there's mention of drilling out the crank case vent hose to 0.75". You might check that connection as well.

All it takes is one poor connnection on any of a half dozen sensors for things to go haywire. I made a quick $100 fixing a friends Nissan Z car after one private garage and the dealer could not repair it. I had an advantage he had even bought the factory service manual. The very first paragraph said check all the sensors for corrosion. The car would start run a few seconds then shut down. The throttle position sensor was corroded, by chance it was the 1st thing I checked.Admittedly Nissan and Chrysler are two different brands and two different systems. BTW the dealer told him he had a bent crankshaft, and had charged for tearing down the motor.He had spent more than $1000 dollars. He just handed me the c-note out of gratitude.Nissan has some cool engineering, the PCM is self checking and has a little green light on the case eliminating the PCM as the cause for any problems.
