had some luck.
replaced brown wire and it seems to idle. also, IAC wire was bad so I fixed it an now it idles. Not getting any DTC codes.
However its running very very rich:
The car has no CAT, and hole in pipe right before muffler.
Also th EGR bark nipple is broken off.
I assume with no backpressure the EGR system isnt working properly which could be giving me this rich situation.
Think the lack of CAT and subsequent EGR issue is throwing my car into failsafe mode making it run rich?
I'm not getting code 41 anymore, but its still rich and smokey. Compression is also 150 cold so dont think its rings.
