I agree, lots of good info, but there should be a warning, and I do not agree that the EHM does all those wonderful things that it is claimed to do, I would run any one of you with my dirty old MAP any day, I only took mine out once, and I will not take it out again unless it fails or does any of those terrible things that is claimed to happen with out the EHM. But since all the Map really does is compare RPM to temperature, I kind of doubt a little oil is going to affect it, and the liquid coating might actually give it better temperature transfer then dry?
Well, the one "real" thing I have done since purchasing my Jeep was to clean the MAP. It's not a case of it being coated with a little bit of oil. Mine was caked solid. And there is absolutely NO question whatsoever that my Jeep's behavior changed once the MAP had been cleaned. My MPG actually went down, but that's because it's so much more fun to step on the accelerator now (no question about increased power).

When the sensor is dirty the CRD will experience decreased fuel economy, decreased power, increased turbo lag, worse drivability, hesitation etc.
Roll your eyes all you want, but I noticed
significant change once I cleaned my MAP.
I have ordered and received my ProVent, and will be installing it soon (after reading all the threads, I believe it's a much better solution than the EHM). I also plan on doing quite a few more of the things suggested on Sam's Noob list (replace Turbo Inlet Hose, replace CCV hoses, upgraded Hayden fan clutch which I've already received, remove exhaust choke point, etc.).
I do think it's important that people be reminded of the dangers that can come from screwing around under the hood though, so thanks for that!
