2002 escalade my service engine light is on. Code 107.. Help Please
I have a 2002 escalade my service engine light is on,I checked with code reader and got code 107 absolute manifold low pressure. I looked it up and it means Bad map sensor. So I installed a new map sensor and erased the code. But engine light is still on and 107 code still appears on code reader. I cant seem to figure out what is the problem. The vehicle seems to run good but it has been sitting for a few years. I did change the oil and flushed radiator,changed air filter. I need to get a smog but cant with light on. I thought maybe someone on this site might of had this problem. I would very much appreciate any help/info someone might be able to share with me. Thanks for your time.
