strange cold start issue
ok guys, i have a strange cold start issue, not your normal "won't start" issue.
The gpr checks out ok, and the truck will start fine when it's cold (coldest it's been is about 15*) as long as i cycle the gp's maybe twice. it will start right up and idle smooth for about 5 seconds, then here's where it gets strange...after starting and idling smooth for 5 seconds or so, it will start to lope really bad and idle goes way down. if it's not extremely cold it will usually smooth back out after a few seconds and be fine. if it's colder than say 25* it will die, but it will start right back up and run smooth again. sometimes does it 2 or 3 times before it will stay running. i think the glow plugs are working ok because if i don't cycle them it will not even attempt to fire off. when it tries to die, if i give it a little go pedal it will keep running, but it runs rough for about 20 seconds before clearing up. when it runs rough like that it smokes white.
i was wondering if it might be the intake heater or feul bowl heater maybe? any ideas? i would think if the gp's are not working correctly that it wouldn't even start as easy as it does? am i wrong?
