Think of it as an oppertunity to upgrade your green machine. Drop that engine in the DD, LS1 in the green machine. If you think about it, it's really your ONLY choice.

My 95 passes just fine with no EGR. I'd guess yours would too.
Sorry for the thread-jack. |
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.

lol @ $1500 for a cast 10:1 bottom end and freshened-up VVT or regular head from Day Custom Engines, lol.

If you need a compression tester I have one.

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 have a spare CAS, spare O2 (they're like $7 anyhow), and pretty sure a stock pulley.
|
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.

Now we're talking.

What Rob said.
Let me know if you need anything. I'd offer the motor, but it's a 1.6L. Coming out soon for something with a little more balls. |
I've got a spare 4 wire o2 that's all wired up and a cat you can borrow.
|
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 fucking roof. Specifically a misfire from running super lean. |
