I purchased an AC/Delco replacement EGR valve for the 1988 Fiero 2m4 (4 cylinder) engine.

The kit came with 11 or so washers.

Here is my problem: The directions state "Find your code from the previous EGR valve to locate the washer for your new EGR valve".
I found the code but the code is not listed on the new part list.

I searched google: Can't find what I need....
I tried on washer, that tripped the check engine light.
I tried the "medium hole" washer, that tripped the check engine light.

Does anybody know the washer #?

Thanks!

One of the first things I replaced was the EGR. I do not recall it coming with any washers. I think I got mine from Autozone, I don't recall the brand. It came with a soft metallic looking gasket, but no washers. '88 L4 Auto

I cannot find either code on the list of washer codes. I guess I will continue trial and error Next up, smaller washer! :P

I've seen this a few times with the comment "I can't find a number on the chart that matches the original EGR I took out. So how can I match the washer size?". Actually folks it is fairly simple and I've done this on many cars.

1. After removal, you will want to TRY to match with the chart.

2. If this fails (you can't find a matching number) take a dial caliper and measure the orifice of the original EGR.

3. Measure the inside opening of the washers to find the one that is closest to the original EGR.

Once you get one that is close (usually within a couple of thousands) install and test. 99% of the time it should be right and work correctly.
