If so, MAP sensor needs replaced. RRB |

Not too hard to see- that is a good thought-check it key on then key off checking for 55-60lbs key on and when you key off it should not immediately bleed off-should hold for 5-10 minutes minimum. This could unveil your issues then post your results and we'll go from there. Good luck! JP |
