i believe codes were 32 and 32...egr function and knock sensor (respectively)...welll i decided to replace the knock sensor first as well as the electrical connector that goes on the knock sensor...i had to splice the electrical connector wire to attach the new connector...anyway after replacement i reset the ecu and have been driving for the past 2 days waiting for code 32 (egr function) to come up since i havent fixed it yet...but so far no engine codes for past couple of days...can anybody explain that to me?...thanks
