Hey all -- Quick question for anyone who knows. I want to pull the CHRA (only) -- I am swapping it with another matching one. It seems that I have to remove the band clamp, etc., but will also need to remove a few cooling lines and such.

Here's the question: Will I be able to only disconnect those ...

Okay -- finally got to it some more! Long story short, it has a new fuel pump. But, quickly, here's the story:

I was able to ensure that the duty cycle signal was getting from the ECM to the PEM. I opened up the PEM and using the freq setting on the multimeter, was able to match it with the same ...

One interesting thing that I can't entirely confirm, but seemed this way, is that it seems to be happier when going -- such as cruise/on the throttle. This may be entirely not the case, but it seems like when it has begun to act up has always been around the time of off throttle, idling, or trying ...
