It *could* be a C&L MAF. If it's not a C&L 73mm MAF then the MAF is more than likely your problem. The ONLY FACTORY MAF that will interchange with the 55mm MAF found stock on 89-93 5.0 Mustangs and 91-93 5.0 T-birds is a 70mm MAF housing and sensor (with part number F2VF) from the following cars:92-94 Crown Vic, Grand Marquis, and Town Car94-95 Mustang V6 or V8 Quote Selected
