I have a 1994 Volvo Penta 5.7 Gipmda . I had a Jasper long block installed in december and made a deal with the mechanic to bring it in in April for final adjustments. He told me it was not idling correctly after the install so he winterized it and I took it home for the winter. I brought it to him and he said there was a problem with the Map sensor. He called me two days later and said the boat was all set to pick up. I picked it up and immediately brought it home to run it. I started it up and it ran well and idled well. So I took a look around and noticed the mechanic had moved the MAP sensor forward of the throttle body and cut the vacuum line attached to it leaving the end open. He also plugged a vacuum line coming from the back of the throttle body with a bolt. My questions are will this cause any long term problems or failures? Where does the vacuum line from the MAP sensor go? where does the vacuum line from the back of the throttle body go? Thank you very much in advance for any help.
