Hi, I have 95 maxima SE auto and as soon as I installed RVM UDP which I got from ebay I'm having problems with the car. The car starts much harder and the check engine light is always on. I checked the computer codes and it says something like "check UDP sensor" but I checked it and it works fine. Does anyone know if this problem go away? Thanks in advance any experiences with aftermarket UDP will be helpful.

 

If you still have the stock pulley, don't throw it off just yet. Here is the problem:

The notches on the timing ring is not "alligned" with the stock pulley. One of these notches is off by only 1/8th inch.
