My location is Trail BC (Canada).

I thought EGR would help the diesel warm up quicker in the winter during cold starts. Also feel better about a cleaner exhaust. Its an odd problem though, with MAF plugged in, will stall or buck/ hesitate just off idle, then EGR light comes on. Did same before and after EGR was replaced, runs fine with MAF unplugged, but the CEL is always on. I should try blocking it off.
