Erratic idle and knocking sound

[KJ75]

I left the EGR as it was, which is blocked with gunk, hence my rough idle and flat spot on acceleration.

I simply backed up my current ECM, and uploaded the new one (HrastProgrammer's 513 EGR/FCV delete - stock).

Yeti from lostjeeps advised:-
"in this file the FCV remaining always open , but it will close at shutdown .......and reopen , like normal operation , and the EGR is always off , this allow more boost to entering inside the intake manifold"

I read all 36 pages of that particular forum, before I worked up enough courage to do this myself.

Thanks pal, I will be giving it a crack as soon as the cable gets delivered.

ps..
Once I uploaded the new firmware, I had an engine check light come on (regarding EGR). I simply cleared the codes and it's been good ever since.
