[QUOTE="TVSCobra, post: 9698998, member: 64473"] You need to check the short term and long term fuel trim. Also look at both the precat 02 sensors and see if they are switching should be between .1volts and .9 volts at idle and cruise. Want are your MAF counts at idle? You may want to get a can of brake clean and spray around the intake tubes and pcv area and see if the engine changes pitch. This is a easy way to find vacuum leaks but it doesn't always work.
