3Pin Posted February 14, 2006 Share Posted February 14, 2006 Check out this thread for a decent picture of under the hood http://www.ultimatesubaru.org/forum/showthread.php?t=51974&highlight=egr+solenoid This link talks about differences between a MAP and a MAF http://www.cobbtuning.com/tech/airflow/ engine type and year are kind of important. If you need a MAF, I have a used one listed in the classified area. Good luck! Link to comment Share on other sites More sharing options...
eventoday Posted February 14, 2006 Author Share Posted February 14, 2006 sorry it is a 97 subaru legacy outback 2.5l dohc. manual. my haynes manual says something about pressure sensors are only in automatic and turocharged. also if anyone has time or knowledge. i just rebuilt my engine. timing belt pulley broke so i had to have a valve job done. it runs really really good now but when autozone plugged in they gave me a #2 cylinder misfire code. the car seems to run to good to be running on 3 cylinders and i am under the impression that since it has a coil pack number one would have to misfire too? any help would be great i spent all my money rebuilding and live in califorinia and now i have to pass emissions thanks again jake Link to comment Share on other sites More sharing options...
3Pin Posted February 14, 2006 Share Posted February 14, 2006 I had a 95 2.2 automatic and a 95 2.2 manual. The automatic I think I had the same error, and I replaced the pressure sensor marked #4 in the previous usmb link. The manual 2.2 didn't even have a pressure sensor near the strut tower. Try a new spark plug, or wire to isolate the bad cylinder perhaps. Link to comment Share on other sites More sharing options...
eventoday Posted February 14, 2006 Author Share Posted February 14, 2006 hey i was just thinking after i put the engine back in i had left a couple of air hoses off. i started the car and then the car idle rough and stalled. i figured out what i had done wrong. would that lead me to having trouble codes since i never reset them.
