Pathfinder Posted January 15, 2014 Share Posted January 15, 2014 I was driving down the PA turnpike with the cruise set. All of a sudden the car looses all power. Cruse shuts off and Check engine light comes on (SOLID) and the cruise light is blinking. When reving past 4k the tac bounces almost like its hitting a limiter...and has no power. Car also now as a slight knock when starting. Also knocks when reving in neutral. Checked the tranny fluid and it is a little low. Walmart didn't have tranny fluid or a code reader so I'll be hitting up the parts store tomorrow morning. Any suggestions as to what this might be? Just goggling around I have come across Limp mode as a possibilityAlso read that a guy had his timing belt jump 2 teeth...which scares me because my timing belt it past due. I have been waiting for the weather to break to do it. 2007 legacy 2.5i 4EAT 115k miles Quote Link to comment Share on other sites More sharing options...
uniberp Posted January 15, 2014 Share Posted January 15, 2014 Did the car have its timing belt service done at 105 miles? I've heard of more than one timing belt tensioner failures, I think I caused one myself once, by compressing it too quickly. The knock may mean it has slipped its timing which can cause internal engine damage. If all this is greek to you, do not drive it until it has been properly diagnosed.

Waiting for the weather to break.. But I was 30 miles from home and made it back... Idk if I got lucky or its something else... If it was the timing belt would it run perfectly before 4k rpm? It only goes wonky at 4k Edited January 15, 2014 by Pathfinder Quote Link to comment Share on other sites More sharing options...
idosubaru Posted January 15, 2014 Share Posted January 15, 2014 first guess is the timing belt tensioner is failing. it's knocking at idle, which i've seen happen before and it can sound really loud and ominous. it may be artificailly loosing timing under load. i would not drive the car like this. it's an interference engine, if the timing belt breaks then valves will bend (unless you're really lucky). then it'll need a complete head job, rebuild, replacement, and $1,500+ or hours and hours of repair. the timing belt, pulleys, and tensioner, should all be replaced. Gates kits are like $130 on rockauto or amazon for everything. it can be done in an hour...probably not for a first timer but it's not hard. the new timing belt tensioners are known to have issues and fail and knock at start up and probably not maintain proper timing under load. they should always be replaced as well as allt he pulleys (which come in the kits mentioned above). for a more general approach: flashing CEL means multiple cylinder misfire and needs addressed soon/immediately. any advance auto parts, autozone, or other chains read codes for free. have i read and post them here. could be ignition related: plugs and wires. use Subaru wires and stock OEM NGK plugs it could be timing component related, artificially affecting timing under certain situations/loading.

idosubaru Posted January 15, 2014 Share Posted January 15, 2014 (edited) Auto zone will loan me a code reader with a 150$ deposit. Taking wifes car over there now... copy. sounds good. actually - you can remove the drivers side timing belt cover, it's only held in place by three 10mm bolts. this shows the 3 bolts holding part #13 in place: http://opposedforces.com/parts/legacy/us_b12/type_19/engine/timing_belt_cover/ item #15 is the timing tensioner in this diagram: http://opposedforces.com/parts/legacy/us_b12/type_19/engine/camshaft_and_timing_belt/illustration_2/ peer in there with a good flashlight and see if the belt is loose. sometimes the tensioner is not notably bad though when they knock like that, they look fine statically (sitting still) but can't hold tension under load. alternately it's located right under the a/c compressor so if the knocking is from that region then it's likely the tensioner. a mechanis stethoscope may help and are only $9.99 at autozone: http://www.autozone.com/autozone/accessories/OEM-Mechanic-s-stethoscope/_/N-255s?itemIdentifier=70131 or order it online and use the "20OFF" promo code and get it for $7.99! ebay has code readers for like $40 or so, great investment and they're so cheap i don't mind throwing them around, taking them on trips, off to help a friend, etc. Edited January 15, 2014 by grossgary Quote Link to comment Share on other sites More sharing options...
Pathfinder Posted January 15, 2014 Author Share Posted January 15, 2014 (edited) Threw a P0028 & P0026... Intake valve solenoid...I'm lost. Running out to check the oil now. Edited January 15, 2014 by Pathfinder Quote Link to comment Share on other sites More sharing options...
Olnick Posted January 15, 2014 Share Posted January 15, 2014 Just googled your codes and this came up--might be worth checking: http://www.justanswer.com/subaru/3y7r4-p0028-p0026-codes-intake-valve-control-solenoid.html Good luck. Quote Link to comment Share on other sites More sharing options...
Pathfinder Posted January 15, 2014 Author Share Posted January 15, 2014 Just went to valvoline. A buddy of mine cut me a good deal. Changed the oil and cleared out the codes... Took a 20 minute ride... They didn't come back... So far so good. Still doing the timing belt next week... Quote Link to comment Share on other sites More sharing options...

Pathfinder Posted January 17, 2014 Author Share Posted January 17, 2014 All is well this far. The throttle is a little less responsive, and the idle is weird when stopping but I'm 99% sure that is from clearing the ECU... Quote Link to comment Share on other sites More sharing options...
