Hello,

 

I got two problems with my 92 Loyale.

 

First, the passengers side hi-beam does not work. The bulb appears fine and it works on low-beam. I'm pretty sure its something simple.

 

Second, I need to change the EGR valve. On my Haynes manual it says to look on the EGR valve to determine what kind it is. However, the EGR is covered in a nice layer of rust.

 

Also the car seems to idle at 1500 rpm, I'm fairly sure this is because of the EGR problem but anything else I should check out?

 

Thank you for your help!

Generally, if there's a problem with the headlights that's only on one side, it's the bulb. They can look "okay" and still be problematic. Try swapping the bulb from the other side and see if it works then.

 

 

 

I THINK any EA82 EGR valve should work on your car. How have you determined that it needs changing? It may just be dirty, or there could very well be a problem in the system that controls it.

 

I really don't know if the high idle would be connected to the EGR valve having problems. It may be possible, I just don't know. It's also possible that the throttle cable is too tight or that you've got a bad temp sensor telling the ECM that the engine is still cold. Have you checked for codes yet?

I'll try the bulb out on monday.

 

As for the EGR, in the Haynes they said to press on the diaphragm to see if the EGR works and I couldn't get it to buldge. The computer gives me code 35 for EGR. I counldn't get the thing off cuz I only had an open ended wrench and it was a little thick to get in there.

 

Thanks!

Don't know if the F/I cars are like the carbed but you should have a vacuum line running to the EGR valve right? I tested my valve by just applying vacuum to it with a vacuum pump, if you don't have a pump you could just find a long enough vacuum line with full-vacuum at idle and put it to it, it should die if the egr opens at a cold idle.

... The computer gives me code 35 for EGR. ...

The computer code is related to the the solenoid that controls the vacuum to the EGR valve. The computer is saying that it doesn't see the proper electrical resistance from the solenoid; could be damaged solenoid, could be disconnected/damaged wiring. The ECU can't tell whether or not the EGR valve itself is working.

 

But that doesn't mean that the EGR valve is OK, either.

IIRC, I thought that 35 was the purge control solenoid, and code 34 was the EGR solenoid?

I think I got the EGR problem solved. Its an old enough car where they can't plug in to check any engine codes out here. Just pull the light out of the dash. It won't fail emisions because of that.... right?

 

I haven't had a chance to look at the car since, but does the throttle body have a set screw to adjust cable tension and hence idle speed? That may be a problem.

 

Thanks for all the help!

They may require that the check engine light is functional. Not sure, but I think that's the way it is most places.

 

The throttle cable tension is adjusted with two 12mm jam nuts right behind the throttle body. There is also an idle stop adjustment with a screw that you're not supposed to touch once it leaves the factory, but somebody may have messed with it. If nothing else works, you could try messing with that adjustment.

IIRC, I thought that 35 was the purge control solenoid, and code 34 was the EGR solenoid?

 

I think Hooziewhatsit is correct on this also though there are some years that the code numbers swap meanings.

 

You may not be out of the woods yet as far as the CEL light being on. In our area, if the CEL light doesn't turn on with the other warning lights when turning on the ignition, the test stops there.

Thanks to Everyone!

 

 

I solved my problems (mostly ). I took off the EGR valve and played with the diaphragm, put it back on and viola, check engine light is gone, idle speed is a shade north of 1000rpm. Got a new headlight at NAPA accross the street for $9 and all the lights work.

 

WHats left? Hole right after muffler, won't be smoged as is. NAPA guy said he should have some exhaust putty in tomorrow for a few bucks. Driver's side tail light is busted and it really really needs a good washing. Other then that its good.

 

Anyone else thing the red fenders give it a lot of character?

 

Need to sell to fund school though
