Mazda B2500 ProblemsHigh Engine Idle with Manual Transmission
A high idle speed can be caused by a poor connection at the Throttle Position Sensor (TPS). Connector replacement kits are available from Mazda dealers and possibly some Ford dealers.
Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.
The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.

The a/c is cold but very little air is flowing from the vents.
Engine light throwing a code for lean. Replaced the fuel pump 6 months ago, and a coil (due to misfire) 2 months ago. Have the TPS, but haven't installed it. Loud rattle on the exhaust. Think that's just a problem with looseness.
