The other thing is, the lady was driving it like granny-low was 1st gear (which it is, but it's obviously not used in everyday situations) - so the rpm's were way higher than they would be in typical driving siutations.
Thanks man. I read up on egr tests, and I'll do those.
One more question:
There are 3 valves of some kind mounted to a bracket on top of the engine. They are plumbed into the egr stuff. What are these, and can they go bad? After I turn off the engine, one of 'em makes a buzzing noise for a few seconds...
Actually, only one of those valves goes to the EGR - it is the EVR (Exhaust valve regulator). It is the component that is used to pass manifold vacuum to the EGR in order to lift it up. The computer opens and closes the EVR to regulate the opening and closing of the EGR.
The buzzing is normal. It is just the vacuum releasing after the truck is turned off.
neato5oh; What part of md.? I live in Glen Burnie.
After you replace the EVR go back to the Emissions testing center (puzzle palace) and request to talk to a supervisor. Explain that the tester used GRANNY and not second to start out in. INSIST on a tester that knows how to drive a GRANNY 1st transmission. If they don't have one there go to another center.
I did this with my '87. Numb***s tester insisted there was something wrong with my T-18. 1st gear only 13 miles an hour @ 4000 rpm.
I got the supervisor after she failed the truck for non drivability(how else did it get to the center, Scotty broke the transporter and I didn't trailer it!)????, and explained to him how she started out in 1st which is a compound low gear and not to be used for everyday driving. Treat it like a 3 spd (2-3-4) and everything will be fine. He ended up driving the test over and passed. She ended up getting suspended. This was 3 yrs ago.
BITCH, COMPLAIN, MOAN, AND GROAN! Most of the testers are 2 brain-celled idiots who flunked auto shop and are marking time on State rolls to get their retirement! And all of them are 3-4 bottles short of a case of beer!!!!!! And usually the supervisor have 4-5 braincells (only 2 of which are working at any one time!) Go for the throat if they mistreat your vehicle.
Got the new EVR. It leaks just like the old one. Checked the EVR on my 93 5.0 Mustang - it leaks too. Did a net search on ford evr vacuum leak, and found an olf thread from this forum. Apparantly these EVR things ARE SUPPOSED TO LEAK!!!
When I first moved to Maryland from out-of-state in the mid-1980s I found the auto inspection processes to be oppressive. The safety inspector tightened a spindle nut too tight on one of my 1980 Chevy Blazer front axles and cost me over $900 to replace a spindle. Maryland's a tough place to own an older vehicle.
