Can anyone tell me a resistance specification for thee old manual trans two terminal IAC? Correct me if I'm wrong but from what I understand in '92 the IAC superseded to a three terminal plug? Unfortunately I only have a '92 FSM and can only find the resistance values for the three terminal IAC Any light shed on the subject would be greatly appreciated! And while I'm at it, what would be the best way to test the Ignitor Module? Thanks in advance! -
I recently purchased my second Subaru, and it has some puzzling problems. When I start it up, it revs up to 1,500 - 2,000 rpm for 30 seconds and then drops down to 1,200. The AT Temp light flashes 16 times, and the Check Engine light is on. When I shift the transmission into gear and try to drive, it acts like the engine is under a very heavy load. At first, I thought the exhaust was clogged, but after checking, I don't think it is. As the car accelerates, it shifts very hard, and when I take my foot off the gas, the car slows down as if it had a stuck brake cylinder (but it doesn't). Finally, when I stop and shift to neutral or park, the engine still acts like it is under load. When I shut the engine off, the drivetrain relaxes, and the car rolls backwards a little bit. When I pull the code from the ECU, it tells me there is a problem with the idle air control valve. I took it off and cleaned it. I also tested the resistance on the pins, and they are around 9 ohms like they should be. Could my idle air control valve still be bad? What about this transmission problem? At first, I thought it might be the Duty C solenoid or transfer clutch, but I cannot read an error code from the transmission. I am using an ELM327 code reader. -
I got a CEL while taking a long trip yesterday in my 2003 Baja. Nothing seemed out of the ordinary with the way the car was driving, but I decided to drive to nearby Subaru dealer and have them pull the code just in case it was something serious. The CEL went out on my way to the dealership, so I skipped it and just drove the car home w/no incident. This morning, I read the code and it turned out to be a P0519 - IDLE CONTROL SYSTEM MALFUNCTION (FAIL-SAFE). I'd gotten this code about 2 years ago, and when the Baja went into limp mode a couple of times, I had the IACV replaced. No problems since. I did some googling, and came across a suggestion to check the air filter cover to see if it was seated correctly. When I did, I noticed that the connection between the air-intake duct and resonator chamber was not mated up properly, so I snapped it into place. Could this have caused the CEL by disrupting the flow of air into the intake manifold?
