Compression was bad 1-year ago. I don't have either piece of equipment in the garage. Sure, I know, just buy one. I already bought a bunch of other ****. I guess its time to find a better car.

Me is starting to think the CAS and or coil pack is bad. However, I've initiated the search for a 1.6 chassis. Hopefully Reverant can switch my MS2 order if I change cars. I have powerful desire to see a 2001 swap in a Mariner Miata.

Ok, so NOx is 4200 (1200 allowable) and HC is 2800 (700 allowable). I do not have any smoke out the exhaust pipe. It will not take less than max spark angle. I have a new MSM PCV valve on it. The tach acts fine, leading me to believe the coil pack and the CAS is OK. I also have an EGR code (flashing light). What do the experienced people think I need to do?

You are running very lean for some reason I think. That is what causes high HC and Nox in the cases I have seen. Things that come to mind: O2 Sensor, FPR, Fuel Pump, clogged Fuel Filter, clogged injectors, Catalytic Convertor .
Advanced spark will cause the NoX to be high and I believe they had a high HC which was attributed it to a FPR in one case. I want to say it was making him lean and not rich.

I'm trying the fuel filter later today, then I'm not sure what's next. I'm guess there's a fuel problem somewhere, which makes sense that I need so much advance to make it idle. I assume that with less advance its opening the intake valve and catching an unwelcome surprise.

Thanks. I may have found someone to help me out though. I did the fuel filter just now and I still get the EGR light. Its funny to think that now I'm going to put MS2 on this car so it will pass the sniffer. lol

Wait, your CEL is flashing? On a '95? I've only seen this on OBDII cars, indicating a catalyst damaging misfire. EGR would explain your high NOx though, and a misfire would explain your HC which is through the ******* roof. Specifically a misfire from running super lean.
