fix the fuel problem. one of my lines was restricted. unfortunately it still runs rough. i pulled the plug on my MAF to see if it would throw a code & turn on the LED check engine light but it never came on. we put a reader on it & there was a code for the MAF. no other codes but we could see the MAP was at 10.8 in park & jumped to 14 when i put it in gear. i was told it should be around 5. when it's in gear it runs really rough now. it's not throwing a code for the MAP so i was told to check for vacuum leak around the intake & MAP. we'll see what happens tomorrow.
right under the MAP sensor is a small vacuum port. where does that go, or can i cap it?
right now it's just open so i think that may be my problem.
