Please help, I hope I am at the right place to ask for assistance, I have a 1990 Legacy with 122K miles. A few days ago on a 98 degree day with AC on the car started running funny at idle. The temp gauge also stopped working; the check engine light also came on. First of all I don’t know how and were to get the trouble codes out. The car runs beautifully above 1500-2k RPM. Sounds like on idle it only runs on two cylinders. I checked the power two the front two injectors and there is no power to them on idle. I switched the fuel injector harness from the rear two to the front two so the front two cylinders fired up. I swapped out the coil unit, mass air flow, wires, plugs etc (I have a spare 1991 legacy sitting around with a busted timing chain). I don’t know much about these cars but it sound to me that the car is set up as sequential fuel injection on idle and after certain RPM it goes to batch fire, just a guess is to why the car runs fine after certain RPM. Is there a cam sensor that works with the injectors? Sorry for the long post and any help in this matter is appreciated. Thanks
