Last year on my way to work I had the diaphram in the FPR let go. The engine was running severly rich... tons of smoke etc... while I limped it home.

Now I'm getting code 44 (lean) after the car warms up and I stop at a light too long.

Thinking about getting a new O2 sensor since it's cheap enough but I was wondering if the FPR going out might have led to its demise?

 

Yes.

 

If you've got a catalytic convertor, the pellet bed might have also gotten screwed up, and could be melted up and ready to clog the exhaust... you might want to check on that, too.

 

Thanks Tom, the converter innerds have long been gone.

I replaced the o2 friday night and still the same. I know that my cold run problem must be somewhere, it's just knowing where to look. I'm gonna research corrent IAC steps at startup now!
