Lou1417 Posted October 5, 2012 Share Posted October 5, 2012 This has been happening frequently. The check engine light comes on and the cruise control light flashes. Car loses power gas pedal doesn't work. Pretty scary on the highway. I disconnected the battery and pumped the brakes to bleed any stored energy. Replaced the gas cap and got a full tank. All was good. Until I got to about a half tank. The same problem happened again. If its not the gas cap making the evap test fail what else could it be? Some one please help Link to comment Share on other sites More sharing options...

Some one please help Evap code would to cause a flashing cel, generally a flashing cel is due to a misfire. I would get the code pulled and go from there. -Mike Paisan http://www.pbase.com/paisan/image/91072632.jpg http://www.pbase.com/paisan/image/145749898/original.jpg http://www.pbase.com/paisan/image/133406601.jpg http://www.whiteline.com.au/images/logos/perf1.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

Kenfrederick87 Posted November 2, 2012 Share Posted November 2, 2012 I just had this problem happen to me tonight on the way home from work. Just bought the car less then a month ago and already replaced the rear right speed sensor. Im going to have to take this car BACK to the dealer tomorrow....i bought a subaru because i heard they were reliable now i am second guessing my choice. I might just throw the keys back at them and walk away, so frusterated. I will keep you posted on what i find out tmw. Link to comment Share on other sites More sharing options...
injanear Posted November 2, 2012 Share Posted November 2, 2012 My wife called today when the CEL came on w/ the flashing cruise. Had her take it by autozone to pull the code and it came back P0171 (too lean). Nothing seems out of sorts with the car, just the CEL and cruise. I'm thinking MAF sensor. Anyone been here before? Anyone know where I can get a sensor? BTW: probable cause from the code check came back as follows Faulty MAF Large Vac Leak Low Fuel Pressure Plugged Injector or Cylinder Misfire Again, no noticeable problems when driving, fuel mileage seems fine.

I might just throw the keys back at them and walk away, so frusterated. I will keep you posted on what i find out tmw. They are good cars. We have a drive by wire system which means no cable from pedal to throttle body. So if one sensor is bad it will throw everything off. Get the code pulled so you know what the problem is. Try to unplug and reconnect the sensor on top of the gas pedal assembly. That might fix your problem. Tps under hood is easy to replace if you need to Link to comment Share on other sites More sharing options...

injanear Posted November 3, 2012 Share Posted November 3, 2012 Could it possibly be the fuel filter. Which would be an ASAP fix for a turbo car? Link to comment Share on other sites More sharing options...
injanear Posted November 7, 2012 Share Posted November 7, 2012 Ok, so I know all of this earth has been plowed many times before, but...Fuel filter is impossible to get to and probably should never be touched. I believe I have my problem fixed. I cleaned the injectors (pretty easy to get to) and changed spark plugs (3 of 4 easy to get to). I ran it about 20 miles an no more CEL/cruise, but we'll see. My guess is if the problem returns it's got to be the MAF since I have no noticeable loss of performance. And yes MAF is simple as well, two screws sitting in a spot where if it were a snake it'd bite ya. Link to comment Share on other sites More sharing options...
