 |
|
Hello,
It's below zero today and I cannot get the engine in my Vanagon to idle at all without significantly tweaking the idle screw on the injection pump.
The engine will buck, shake, and die if allowed to idle. Also the accelerator has a really delayed affect (ie I can floor the accelerator and there will be a noticable pause before the engine responds at all).
To get the engine to idle normally I would need to move the idle screw probably 1/4" in. The engine seems to run fine at higher RPM.
Last time I had this issue it turned out to be gelled Summer fuel in the tank, I added ISO HEET to the tank and have probably run three tankfuls of Winter fuel since then so I cannot imagine that is the issue. I've also changed the fuel filter in the last 50 miles so I can't see reason to suspect it. All of the fuel lines are new in the last 1000 miles and all the connections are tight. Any ideas? I have an electric coolant heater and let it run for an hour before starting the engine, the temp gauge needle never appeared while the engine was running so obviously the engine never got up to temperature.
-Thanks,
Erik |

| Yep, it was pulled out. Turns out the problem was gelled fuel again. Looks like the Winter blend sold around here is only good to a few degrees below zero and it was just a little too cold last night. A heat gun on the filter and ISO HEET in the tank and I'm ready to roll again. |

Is ISO HEET rated for diesel?
I've been using a more expensive blend (can't remember brand) that is labeled exclusively for diesel.

Yes, ISO HEET is labeled for diesel use. |

Up here all the diesel heads I know use Howes diesel treat http://www.howeslube.com and so far I have not had any gelling problems. Kinda funny how many times the minute I mentioned I was new to diesels this stuff would be recommended, and I really appreciated it!
