*could* be the throttle switches. check continuity on both of them, and make sure to wigle the connections good, as it seems as though your problem is intermittent. i guess the only way to do a road test would be to drive without the connection installed for a few days, and note what happens when you think it should crap out on you. when a wire broke on my throttle switches, my "idle stabilizer valve" was my right foot. if i didnt crack the throttle, it would die. once i fixed the wire, the problem went away. check all parts of the wiring for continuity and shorts, and be thorough. *could* also be the knock sensor. #2 is between cylinders 3 and 4, FYI. the motronic sensors can lose their plasic coating from heat and cracking, and can become very exposed. again, since its intermittent, you cant test once and assume all is okay. if the knock sensor keeps coming up after you keep resetting the fault codes, i would figure out what is wrong with the knock sensor. check wiring for continuity and shorts, and visually inspect if at all possible. i dont know if its possible to switch knock sensors, but you might want to try that. switch the connections, i mean, not the whole sensor. as long as your car doenst knock, it doesnt use those sensors anyway. if you get lucky, you might get a fault for KS1 and then you'll know its a bad sensor. just a though, dunno if that will work or not. the airflow plate is a strange thing. i have heard that it doesnt really do anything after startup, but i cant confirm that. i always though the bently test for that was rather ambiguous as well. _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
