seth3030 Posted August 14, 2009 Author Share Posted August 14, 2009 so i think its between getting a ignition coil cleaning the maf and if that doesn't work maybe its the cat? Link to comment Share on other sites More sharing options...
Fairtax4me Posted August 15, 2009 Share Posted August 15, 2009 Cleaning the MAF is easy and costs $5. Might as well start there. Does it do the same thing if you accelerate hard (put it on the floor) on flat ground? Link to comment Share on other sites More sharing options...
seth3030 Posted August 15, 2009 Author Share Posted August 15, 2009 not usually but it depends how hard i push it it has before, when i do push it hard there is quite a bit of lag or throttle response but i can tell it is trying Link to comment Share on other sites More sharing options...
Subaru Jim Maple Ridge Posted August 15, 2009 Share Posted August 15, 2009 Slim chance, but easy to check. A plugged gas cap allows a vacuum to build in the tank, making it hard for the pump to deliver enough pressure. All you have to do is pull over right away, shut it down and open the cap. If you hear air sucking in, you found it. Good luck. Link to comment Share on other sites More sharing options...
seth3030 Posted August 16, 2009 Author Share Posted August 16, 2009 i dont know if it matters a great deal but i really think the only times it ever does it is up hill flat ground its fine Link to comment Share on other sites More sharing options...

Cougar Posted August 22, 2009 Share Posted August 22, 2009 At this stage, you may want to investigate for a problem in the exhaust system. Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 22, 2009 Share Posted August 22, 2009 Had a friend with a postal wagon that would do the same thing. He could drive all day with it but there was one hill he would make it up halfway and it would start misfiring. Stop, let it wait 5 mins, it would fire back up and make it the rest of the way up the hill. Fuel pressure was good, filter was clean, no codes, so we threw parts at it off my pile of spares. A different coilpack solved it. Apparently the coil was marginal and it would overheat and open under heavy load. They don't go bad very often, so grab a coil off a manual transmission car. Coil should say "diamond" on it, they're supposed to be better. Link to comment Share on other sites More sharing options...
seth3030 Posted August 28, 2009 Author Share Posted August 28, 2009 new coil nothing changed, o2 sensor changed, air filter changed, fuel filter and fuel pump changed, new spark plugs and wires, new gas cap, still the same problem, im about to ghost ride this thing off cliff Link to comment Share on other sites More sharing options...
shadetreemech Posted August 29, 2009 Share Posted August 29, 2009 A '94 should have an OBD 1 computer control system. OBD 2, which standardized codes among manufacturers, started in '96. This means that your onboard diagnostics can be read by Subaru compatible code readers. You don't have to go to Subaru. Stop in at your local full service auto parts store and see if they can read your trouble codes. If you have to buy a suitable code reader, it should be in the $100 range. Make a few calls to NAPA, etc, and ask what they recommend. Read the codes before you drive it off a cliff. Link to comment Share on other sites More sharing options...
seth3030 Posted August 29, 2009 Author Share Posted August 29, 2009 will there be any codes even if my cel isn't coming on? Link to comment Share on other sites More sharing options...
seth3030 Posted August 29, 2009 Author Share Posted August 29, 2009 (edited) i was reading another post similar to mine and he said that the obd1 said "purge control solenoid" is there any chance this could be it Edited August 30, 2009 by seth3030 Link to comment Share on other sites More sharing options...
john in KY Posted August 30, 2009 Share Posted August 30, 2009 Any chance you could test the fuel pressure going up that hill? Dropping cylinders and lack of power under load suggests to me either a weak ignition or low fuel flow. Link to comment Share on other sites More sharing options...
seth3030 Posted August 30, 2009 Author Share Posted August 30, 2009 i dont think so :/ but ignition how? i put a brand new coil on it, and if fuel flow is low then what could be causing it if i replaced the fuel pump and filter? Link to comment Share on other sites More sharing options...
