This is not as much a complaint as a request for help. Since March of 2013 I have replaced 5 throttle bodies and 3 gas pedal sensors, all oem parts. The problem that happened again today: driving at normal highway speed [55/60] the eml, traction control and brake warning lights all went on. Pulled over and turned off. Restarted, now "service engine, eml, traction control and brake lights" were on. Turned off, restarted, same lighting situation, very rough idle and car would not drive, as it was struggleing for fuel. Unplugged the "mass air flow sensor": car started, displayed no warning lights, drove fine about 8 miles to repair shop. Code read shows, "throttle position sensor", replaced. . Same problem within minutes of driving. A little internet research on e46 finds this an all to common problem with no solution. Thanks in advance.
