I have a 1993 Buick lesabre limited. My check engine light comes on and off as im driving. I got the codes checked and they are maf sensor and throttle position sensor. The car also stalls but when I'm at a stop. It idles real high at times and the abs light never goes off. Also, my air vents don't work, the heat or air doesn't come out but the heat comes from the top by the windshield and by my feet. Also the car shakes when I'm 40mph+. Does anyone have any insight on what the problem is, a lot of parts are new on this car from devious owner but still can't find the problem.
Thanks in advance.
