Ok, so i disconnected the mass airflow sensor, and drove around for about a half hour with no problems, no hesitation no lag...RAN GREAT, like all great volvos do....now i have some more issues..lol...my a/c hose blew the other day....speedometer just stopped, RPM's are still working.....odometer and trip counter havent worked since i bought the car....right now thats all i have, i will continue to test and run my vehicle. i plan on doing a full tuneup and hope and pray everything turns out for the better....if anyone could assist me in these issues it would be greatly appreciated...
