Three of the six fuel injectors started leaking at the body/wiring terminals. One injector was leaking enough to witness a frequent drip (approximately one drop/second) from the body, and the other two were visibly wet (have video of this, as well). Leak occurred any time the fuel rail was pressurized or the vehicle was in operation. Smell of fuel both inside and outside the vehicle were what prompted inspection. Issue was solved by replacing all three leaky injectors with new ones (no issue for about six months now). Am concerned, not only because there are three of the original fuel injectors still on the vehicle, but because the fuel injectors may have been leaking for quite some time while still in use, only being noticed once the leak became more substantial. Was advised to report this issue here, as it is both a safety and emissions issue, and is apparently a fairly common one for this vehicle model/year.

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 struggling 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.
