96 Computer Problem
96 Mustang 3.8L w/86,000 miles. Check engine light on with OBDII of 1151 and 1174. Mass air flow sensor changed. Now the problem, the car was sending info to the shop's computer. When accelerating the motor, the computer would take almost a minute to indicate an RPM acceleration. The computer was hooked up to another Ford and performed as it was suppossed to, only had a delay on my Mustang. The engine accelerated with no hesitation, but the computer lagged behind instead of showing instant RPM increase. Any help would be greatly accepted. The mechanic has since cried "uncle".
