We've got a code 36 in progress
I've had this code before on my 87. It has to do with the MAF sensor. It's come up twice in the past month or so, but after I read the code and check all of the connections and everything (which looks fine) and restart, the code has cleared. Relays are the next to check right? The code tripped this morning so I didn't have a chance to check the helms book yet.
What would be the cause for it coming on every once in a while?
I'm also getting a low coolant light coming on, but only after going downhill for a long time (or so it seems), but that's another story altogether.

You have to look at the MAF burn off relay. It is behind the battery. It is either of those 2 relays, both relate to the MAF sensor.
About your low coolant light, mine used to come on a couple of days after I got my car. After I did a coolant flush and topped it off with a 50/50 coolant mix, it has never been on ever since.

I had this on my '85 and it would shut down the engine. It would start up OK but would stall intermittently. The MAF sensor, which you can buy after market, is located at the neck of the air intake. It's held in with 2 hose clamps. It's basically 3 strands of fiber which senses the air intake and calibrates the engine, I think. Sounds like the sensors are bad or about to go south so just replace and it should clear the error. As I remember, the part wasn't cheap...well according to my mechani$.

Just did this on my car a few weeks ago. Got the relays (both the same part number) at NAPA for about $14 each. I replaced them both. No check engine light since.

So now that I've put the new relays in, what should I expect difference wise? Other than the obvious engine light not showing up again. Assuming this was the problem, should it change the idle, smoothness of it, gas mileage, anything?

Saves being towed home!
Watch it though. Lots of codes will point to the MAF. And sometimes its not the MAF. At 80+ bucks the MAF is not the first item to start part swapping. Read the Helms and go throught the trouble shoooting charts first.

Yeah, I know because this one time, my original 16 year old IAC was leaking some vacuum and air was getting sucked in the intake without passing thru my MAF, causing a code 33. Don't forget, bad IACs sometimes will cause your car to stall out intermittently when you let of the throttle.

MAF Relay tests?
Is there a way to test if the MAF Relays are good? I get a SES light with Code 36 about 1 time per year and then just swap out both the MAF Relays. Now I have about 6 of them laying around.
