ShawnW Posted September 13, 2005 Share Posted September 13, 2005 There isnt a way to recondition/repair them. Used or new is about the only way to go. Used is considered illegal but if you do the work I dont see how it would come back to get you. Quote Link to comment Share on other sites More sharing options...

I was wondering about *ahem* "reconditioning" them to allow better exhaust flow, not necessarily for functionality. Any idears there??? Note: I am in a non-emissions checking area/state.

d-a-g Posted September 21, 2005 Share Posted September 21, 2005 I went thru this with my 82 GL 4WD Wgn - at about 265K. Was running about 12 psi compression in one cylinder. Rebuilt engine, didn't fix it. My shop (Smart Service in north Seattle - Subaru only, all factory trained techs) finally found the problem - fuel filter, but not the plastic one under the hood, there is one somewhere between the tank and pump. Fixed the problem. Car is now at 305K and going strong. Getting 27mpg mostly highway driving with EA81 engine and 4 spd d/r trans. Quote Link to comment Share on other sites More sharing options...
4WDFrenzy Posted September 21, 2005 Share Posted September 21, 2005 If you have a welder, I would suggest buying a universal high-flow cat, get some piping made and weld that sucker in place. Quote Link to comment Share on other sites More sharing options...
Log1call Posted December 30, 2005 Share Posted December 30, 2005 The knock sensor kicking in and causing the timing to be retarded can cause that. Depends how much power it has to start and how much power it looses that will really tell you, there is no substitute for experiance. If the drop off in power is not too dramatic you could try additive to raise the octane rating or disconnect the knock sensor from the block but leave it connected to the wire and try it but be carefull not to let the motor, "pink". You need to tape the sensor up out of the way of being knocked while you go for your test drive. Quote Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted December 30, 2005 Share Posted December 30, 2005 SPFI Loyales dont have knock sensors. Only MPFI Turbo's and N/A MPFI XT's -Brian Quote Link to comment Share on other sites More sharing options...
Allouez Posted December 31, 2005 Share Posted December 31, 2005 The post about the "other" fuel filter (near the gas tank) is a good one. I'm having a very similar prob. w/my 83 wagon, and have replaced nearly everything that it might be and have yet to solve it, though the cat. is up for surgery this coming week. Mine acts as though the choke isn't opening properly, but it does. If I solve my prob., I'll be sure to post it. Definately check that other filter if yours has one. My father always said: "Check the cheep stuff first". Thanks all for the great posts. I'm learning a lot! Quote Link to comment Share on other sites More sharing options...
Mantonite Posted January 1, 2006 Author Share Posted January 1, 2006 FIXED!!! Got a TPS from a low(er) mileage Loyale, swapped it out and now I have throttle response! It took a little more than I expected to get the old one out (just two screws and a connector, right?) but it was worth it. Hopefully I'll even get better gas mileage out of the deal. We shall see... Anyone rebuild old TPSs? If not, I'll tear into this one to see if it can be done/if I can spot the problem. Thanks for all the help!!! Let me know if you want more details.

D-Cal Posted January 1, 2006 Share Posted January 1, 2006 Could be a failing fuel pump. It can't deliver the volume the car demands at WOT and starts leaning out costing power. Tie in a fuel pressure gauge and zip-tie it somewhere on the windshield that you can see from the drivers seat. Note the fuel pressure under WOT.
