Does it misfire under load like when you press on the gas peddle after slowing down then accelerate or at idle. When you say spark plug did you mean all the spark plugs?

SOURCE: SERVICE ENGINE SOON

You can't tell what the problem is just by the presence of the "check engine light." Many sensors can set off the light. You can connect a diagnostic analyzer to the vehicle and it will spit out codes that you can look up to see what the problem is. That is what most shops do, or you can buy an analyzer and do it yourself. It may be harder to find one for a 1987 car though

SOURCE: ASM 2525 NO ppm TAILPIPE EMISSIONS failure

I have a 94 Tbird with a reading of 790 NO ppm at 1871 RPM, I put about a liter of water into the intake at about 2000 RPM and changed vacum lines to EGR valve,(may have been cracked), now the reading is only 214 NOppm at 1348 RPM. This much change I don't understand. Maybe this info may help someone.

CEL P0431 but passed smog emissions in CA - how can I pass emissions if the CAT is damaged? Could it be another issue?


Maybe not your answer, but it is related: Before going to have your car smogged, check your gas cap. Check the condition of the gasket, or o-ring, inside the gas cap. If is already drying out, full of cracks, get a new one. It will not pass the visual inspection. The smog technician, salesman, will try to sell you a new one for $15 when you could get it for $8 at your local auto-parts store. The technician will tell you that if you do not get it right there and then, he will have to fail your car on the visual test and you will have to comeback to have your car re-smogged again.
The cap might still be doing an OK job of sealing the tank, but it won't pass the Visual, especially if the tech wants to sell you a cap. You can tell if the cap is doing its job if you hear a hissing sound whenever you open the gas cap after running the engine fro a while. If it is not providing a good seal, then you might get a check engine light with a code about a failure in the evaporative system.
Just a little thing to check before you go and put yourself at the mercy of the smog tech.
For $15 you could get a locking gas cap, which might be a necessity now with gasoline prices being what they are, now.

Did the 1988 Chevrolet 1 Ton come equiped with a smog pump


Yes they did, and I used to maintain a fleet of them for a certain lath and plaster business in the mid 90's and most of them that I serviced were from around 1987 to 1988 and all of them had a smog pump, and I also had to make sure that they all passed a bi-annual emission inspection.
