Okay I went out and bought a obII scanner today and got code1406 differential presure feedback EGR (DPFE) sensor downstream hose off or pluged/ my engin is a V6 vorteck i dont know how many lieters right know the EGR valve was stuck sollid. claned some of that it moved again i was wondering if this could be a hard start problem it passed enisions about 1month ago but check engin light has been on since we bought the car we were told it was a chemical run through the engin and thier shop was closed to reset the computer (lying basterds). well anyways I was also wondering the best soulution to clean the map dont need a dead car in the garage I am only 16 so no mony for parts realy would like this to be a simple wekend project and dont wory I have the tools and knowlage.

Ok why do you have two threads on the same thing?
