Ok the check engine lite is on and it's got a nasty shudder about 40K and up. Although there seems to be an intermittent miss most times. I've changed the dpfe and that didn't fix it. I know i may end having to get a scan for codes but i'm in canada and they want abit much for doing it. A couple quick questions to start. I have unhooked the fuel pressure vacumm hose (I wanted the vacuum for the egr for a quick test), should the motor idle etc change when i do that. It didn't. And (not really a question) but the idle appears to drop about 100 or so when i put it in gear. I don't remember that it normally did that but it might provide a clue to one of you. I'll be changing the fuel filter shortly (it may not help but it is needed) and as soon as i can find a fuel pressure guage i will be testing that. Any suggestions as to what it might be would be great. Thanks Robert
