Does anybody know if a defective maf sensor would cause shifting troubles. I've posted before regarding my wifes 95 contour zeetec, 150,000 km. Car would experience major loss of power and severe idling trouble with hesitation when pulling away from a dead stop. The only code that ever came up was O2 sensor running lean. I finally after much heartache decided to replace it ( $140.00). After my local mechanic changed it for me I had major shifting troubles. Its an automatic and when it came out of 1st it would chirp the neoprine belt ( felt like a shift kit).I finally took it to the local ford dealer on Monday ( $58.00/hr) and he said that I had a incorrect shift ratio code and that my maf was defective. He cleaned it with something and now it works alot better but I am getting maf codes and some bucking around 80 kmh. It also seems different when it shifts into overdrive. A local junk yard has a maf sensor for $50.00 so I think I will try it but I don't know if this is causing the "bucking". Any thoughts would be appreciated. By the way, great site, keep up the good work.
