1995 GLE : MIL on - dealer can't find problem
Hi - this is a great group! It's my first time here. I read thru all of the FAQs but
didn't see anything on this particular question.
I have a 1995 GLE, ~124,000 miles. Original owner, no trouble with
the car until recently. In the last 8 weeks, injectors 2 & 5 failed
and I had them replaced with no probles. The failures were signalled
by rough running and the MIL light. I pulled the codes from the unit
under the center dashboard and the codes told what the problem was
diagnosed to be.
Early last week, the MIL came on again, but the car ran great. I
pulled the codes again and got 3-4 (knock sensor) and 3-2 (EGR system
hi/low flow). I took it to the dealer to have it checked out and they
got the EGR code but not the knock code. They looked at the EGR system
and exhaust system at least, and found nothing wrong.
After a day & 1/2 of checking the car, they still couldn't find
anything. They reset the light & said that they thought it was just a
fluke and probably wouldn't recur. After I drove 328 miles in
numerous key cycles, the light came back on. It's sending only the
EGR code now. The car is running just great, and if not for the light,
it wouldn't appear that anything is wrong. I'm taking it back to the
dealer on Monday again for a 2nd look.
Does anyone have any idea what might be going on here? I looked up the
EGR code from the FAQ section, and it appears to cover a
lot of ground. But the dealer's techs just aren't finding anything
wrong with the car. The two times this error code/light have occurred
it has been on the 2nd or 3rd trip after a fillup. Gas cap is tight
and dealer said it was holding pressure well. I haven't changed the
gas I'm using either (Shell Premium). I'm just trying to get some
different ideas here.
Help!
Thanks!

Gas cap pressure has nothing to do with the EGR system. That is part of the EVAP system. So, which one are you actually talking about?
What code number did you pull?
Cleaning your EGR port on the intake will likely take care of the problem if it IS the EGR system.
If you mean it is the EVAP system then there is a common failure in that area...which I have no experience or memory of the details.

03-02 EGR Hi/Low flow
Hi - I pulled code 03-02 - EGR system Hi/Low flow. I have that same code stored presently, and that is the only one. I had wondered about the gas cap, since on my last fillup before the light came on, I didn't have the hissing pressure sound when I took the gas cap off. I wasn't sure what category of error code that would fall under, so with it being EVAP, that probably isn't related to my problem.
I have had the EGR code consistently since the light came on, so I think the problem is in that system. My dealer couldn't locate any problem with the car the 1st time around, so I'm going to take it back on Thursday for another look. My car drives/performs great, i just have the concern that this is a problem that could become more serious if allowed to go on.
cheers -

Rochelle,
It won't become more serious but it's a good idea to have it fixed.
I would take it to a different dealer. They should know this problem since it is common in the 4th gen max to have the EGR port clog up right where the EGR attaches to the intake plenum.
