Thanks. I went to the link you provided but the link that is in that thread does not exist anymore. There is no inspection here in Colorado and they don't care if the check engine light is on as long as it passes emissions. Just trying to figure out why the fuel is not burning completely. Can I go to the junkyard and grab an EGR solenoid from another subaru there? Where is it located?

I'm new to this forum and have been looking for answers to why my car won't pass emissions and why the check engine light is coming on and off. I have a 1991 Loyale and when i start it up the CEL usually comes on. Once I'm on the interstate it may go off (or it may not). I just drove it 1200 miles on the interstate and about 1000 of it was with no check engine light. The codes I retrieved were 11 (Crank angle sensor or circuit), 13 (Cam position sensor or circuit), 14 ( Air control valve or circuit), 24 (Air control valve or circuit), and 34 (EGR solenoid valve). My car does not seem to run rough at all as I've been driving with the cel on and off for the last 10,000 miles and getting 37 mpg on the highway. It only has a hesitation in 2nd and 3rd (manuel) when it has not warmed up. Now when I took it to the emissions place it had too high a hydro carbon count (1.5 is limit and mine was 2.3). They said that is becuase of possible bad 02 sensor or needs a tune-up (fuel is not burning completely). I did a tune-up (wires, spark plugs, cap, and rotor) and added bg 44k to the fuel (cleaner for injectors, valves, and piston). Still would not pass. Just wondering if this is all related. Any help would be really appreciated. I have a junk yard close by with 8 of these cars in it so I can get the parts hopefully. Thanks again.
