While driving the engine suddenly died. luckily we were on a lightly traveled road and were able to pull off to the side. the engine would start, run for about one second, then die. while waiting on a tow truck, a gearhead-type friend that i had called to take my wife home arrived, thought about the problem a bit, and unplugged the maf sensor. the engine ran great. it turned out that a defective air filter had allowed debris to clog the sensor. my complaint is that an invalid reading from a non-critical sensor should not be allowed to pull the engine fuel/air/timing parameters so far off that the engine will not run. obviously the engine computer knows approximately what those values should be since it ran great with the sensor disconnected. sensor readings beyond what would reasonably be expected should be ignored. we were lucky that we were on a country road when this occurred. had we been in the middle lane of a busy freeway, or darting across four lanes of busy traffic, this could have been a disaster. *tr
