QuestionQUESTION: Hi again Roland.
I'll be trying to find that EGR valve for my 1996 Voyager after Christmas shopping is done. I have another problem with my girlfirend's 2004 Saturn Ion ( I hate it when cars need work in the winter)
2004 Saturn Ion - Wiper arm is getting loose. The shaft where it nounts into the area where the wiper motor is is up about an inch to an inch and a half.
There is a round button-like cap on the wiper arm. Is the this cap removable? What do I have to do to remove it and can I do any tightening once I get it off?
An Autozone rep tried with a small screwdriver, but couldn't get it off. He said he believes it should come off as he does one or two of these quick repairs a week for customers
Thanks for your time,
Mike
ANSWER: Hi Michael,
I am not familiar with the wiper mechanism of the Saturn. I would suggest that you see if there is a Haynes manual for her year of Saturn and check to see if the wiper mechanism is shown. Or go to a dealer parts counter and ask to see the parts catalog which will have a visual blow up of the parts.
Let me know which engine you have in the Voyager and I can tell you better where to find the egr. There are 4 possible engines so I can't go through the details on all of them.

QUESTION: Hi again Roland,
The holidays were a little more hectic than usual. I have a 3.0 liter 6 cylinder engine.
The van doesn't have the idling problem when it first starts up but after it gets warm. It's done that consistently the last few times I have taken her out. It will ride okay for a while then it will have the stalling problem when I take my foot off the pedal. If I stay on it slightly it will run fine
If you need more engine info I will try to provide it
Thanks again for your time and experience
Mike
ANSWER: Hi Michael.
The egr is located toward the front of the engine, on the top side. You will see a small pipe that branches off the exhaust manifold next to the radiator and which runs up and back just in front of the valve cover. You will see the egr mounted in that pipe. It has a round top with the vacuum hose, and the body of the valve is in the pipe proper. Between those two parts is a flange and hidden inside the flange is the valve stem, a rod with a slot. You put the tip of a screwdriver in the slot to move the valve stem back and forth, against spring-action that tries to close the valve. It should move freely and close tightly to a dead stop via the spring action. If it is sticky and not closing on its own then spray some WD-40 on the valve stem where it enters the body of the valve and work the stem some more. See if that solves the problem. If not then you may have to remove the valve and clean it out.
The other thing to do is get fault coded using the ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remains 'on', to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat the process to be sure of an accurate flash count set. Tell me the flash counts in order of appearance and we'll go from there.

QUESTION: Hi again Roland,
Yes I am a procrastinator. I found the EGR valve on the backside of the engine attached to a plastic piece. The plastic piece is round with 3 vacuum hose connections and one two-wire electrical connector attached to a cylinder shaped thing piggy-backing on the round plastic thingie (I really impress my girlfriend with this technical jargon). I can't get a clear enough look at the valve, because of where it is mounted, to insert a screwdriver in to manipulate anything.
Of course being a creative problem solver I was pondering removing the vaccuum hose from the valve and squirting some WD-40 into the opening and squirting some around the valve hoping to accidentally lubricate an effective spot... any merit to that idea or is that a "enough information to be dangerous" kind of thing?
I did the code trick and I came up with 1-2-4-2-4-2-5-5. I did it twice to be sure.
Hope this helps you to help me,
Mike
AnswerHi Michael,
This is the same question I answered yesterday:
Hi Michael,
The 42 code says there is something the matter with the autoshutdown relay circuit. If that relay is not energized properly that will cause the stalling of the engine. You might try switching the autoshutdown relay with another relay in the power box under the hood, one that is not crucial to operation, and see if that solves the problem. If not, then I would try spraying some WD-40 on the body of the valve (the part that is attached to the pipe, hitting specifically the side of it that is toward the balance of the device because that is where the valve stem enters the valve body. It would help to move the stem by hand, but it you can't you can't.
