1999 Ford Ranger XLT from North America - Off Topic Comments

My 99 Ford Ranger had these same issues. Wipers would turn on by themselves, dealer recall cleaned up that issue. At sixty two thousand miles, my O2 sensor failed, I replaced (Easy). I also have a noise that sounds like the belt, mainly when it is wet outside. I don't think its the belt, maybe a noisy pulley. I have had the belt replaced twice, still same problem. At about a hundred thousand miles my speed sensor failed (Speed-o-meter didn't work, brakes locked up, ABS light was on, and Transmission wouldn't shift from first) very noticeable. I replaced the speed sensor for around $40.00. Mine was Magnetic and fit in the differential, not the kind that fits in Transmission (Mechanical). At about one thousand five hundred fifty miles, bad idle. AC Clutch keep kicking on and off. Engine started rough, and ran better once warm. I replaced the Intake Control Solenoid for $88.00 (I believe this was caused by cleaning the throttle body junk and carbon build up). So far so good. I still have the pinging noise though. I was told to use higher octane fuel. I tried that and it helped a little. I did have the throttle body cleaned at a local shop for about $40.00. It was a advertised throttle body cleaning at It runs with less ping than before. But still pings on occasion (around 55-75), not nearly as much though. I also switch back to low grade regular and ping is still much lighter, but is still there.
