stonedmonster Posted October 25, 2013 Share Posted October 25, 2013 Hello I am new here I just bought a 93 loyal fwd 1.8l 5 speed and it is my first Subaru. It has a bogging out issue when speeding up it idles fine but if you push the gas pedal down more than about an inch it bogs out, it does it in all gears. I am clueless it runs fine just got to accelerate slowly, anyone know why??? anything helps thanks. Link to comment Share on other sites More sharing options...
MR_Loyale Posted October 25, 2013 Share Posted October 25, 2013 Check for vacuum leaks. Also could be a fuel delivery issue. Link to comment Share on other sites More sharing options...
stonedmonster Posted October 25, 2013 Author Share Posted October 25, 2013 okay, I did not think it would be fuel unless its getting to much. It runs great it idles smooth and I can drive it but got to take off slow if I push the pedal to hard it just bogs down really bad or if you rev it, but I can rev it up if I just push lightly. it looks to have a new fuel filter in it and the pump don't seem to be making much noise, Someone had suggested the throttle positing sensor would that cause this??

Lou Baroo Posted October 25, 2013 Share Posted October 25, 2013 I had a similar problem. We found several issues: 1) wrong fuel filter. No kidding The correct fuel filter is very large and sits in a bracket that is mounted near the driver's side strut tower 2) TPS "issues" (of which there were several) First it was not mounted securely and was off placement Then a mechanic I had working on it properly "calibrated" it - a procedure I am not familiar with Link to comment Share on other sites More sharing options...
ruparts Posted October 25, 2013 Share Posted October 25, 2013 hi, if the car has been sitting for a while , old gas is notorious for this condition, putting a couple hundred miles with new gas is the cure for that. second check the ignition timing, you must have the diagnostic connectors connected ! and set it with a timing light, then disconnect them for daily driving after the adjustment,,, they might be connected now , if so , that could be your problem since that will cause the timing to not have advance. next check the coolent sensor and the connectors to it, they usually have the green corrosion and this is the temp sensor that controls the FI system. if these few things don't get you going then maybe 1 or both your timing belts have jumped a notch , easy to check , remove the outer end covers from the belts and line up the 3 timing belt marks on the flywheel with the bell housing pointer and see if the cam pully marks are exactly , 1 straight up and the other straight down,, if so the belts are right. the throttle position sensor may cause problems but if it's not been messed with don't do that till after these other checks first.

BoxerRebellion Posted October 26, 2013 Share Posted October 26, 2013 Never rule out the simple or obvious. I remember I had a '94 Legacy. Had the same symptoms as you're describing. (Freaked me out by the way) Turned out - It had a bad plug wire. Electricity was arching up the side of the boot. Replaced 'em and there-yeh-had-it. Start with what's easiest to access/diagnose. Work your way up that chain. Your check engine light isn't ON? (Not that it matters nearly as much with Soobs) If it is ON, AutoZone will run the codes for free. Sweet huh?

Gloyale Posted October 26, 2013 Share Posted October 26, 2013 If it is ON, AutoZone will run the codes for free. Sweet huh? Autozone only scans OBD II cars. Any 94 or OLDER subaru needs codes pulled using D-check or U-check modes (green and black connectors) Link to comment Share on other sites More sharing options...
stonedmonster Posted October 26, 2013 Author Share Posted October 26, 2013 Okay that's were ill start, and no check engine light. it does better after she's good and warm its not as bad as when its cold. when its warm I can hold the pedal down and it will bog down pretty bad but if If I keep holding it it comes back after like 30sec Link to comment Share on other sites More sharing options...
stonedmonster Posted October 26, 2013 Author Share Posted October 26, 2013 I am not familiar with pulling codes on thease old soobs how do I do that?? and if it had a code would the check engine light be on? Link to comment Share on other sites More sharing options...
Subarocket Posted October 28, 2013 Share Posted October 28, 2013 My car did this too. Pull off air filter, make sure she's clean, spray sensor with carb cleaner or it looks mucky, let dry, make sure everything goes back together tight. Presto. Could be real simple Link to comment Share on other sites More sharing options...
ivans imports Posted October 28, 2013 Share Posted October 28, 2013 Feul pump / preshure / volume problem or mising intake plumbing or inproperly conected intake plumbing Link to comment Share on other sites More sharing options...
Rust Posted October 29, 2013 Share Posted October 29, 2013 Most likely fuel issues, dirty injectors/lines /filters ect. Had very simmilar symptoms w/ my 93 loyale. swapped all the plugs/wires, ect. even tried swapping fuel filters/checked and re-checked all the vacuum lines. Nothing fixed it. Eventually it got better, whatever was clogging up the lines must have worked its way through. Link to comment Share on other sites More sharing options...
stonedmonster Posted October 30, 2013 Author Share Posted October 30, 2013 haven't had time to do anything yet to find the issue but it DOES have a check engine light on. the previous owner had put black tape over the light Link to comment Share on other sites More sharing options...
Subarocket Posted October 30, 2013 Share Posted October 30, 2013 I don't think you can be mad at someone for putting tape over the cel. It's not that sneaky and you could have questioned the tape. Don't write off the air intake issue I suggested. It can be simple. Link to comment Share on other sites More sharing options...
Gloyale Posted October 30, 2013 Share Posted October 30, 2013 the previous owner had put black tape over the light I don't mind the tape. It's when people take out the bulb or cut the wire to disable it that I get peeved. Link to comment Share on other sites More sharing options...

stonedmonster Posted November 2, 2013 Author Share Posted November 2, 2013 the light wasent a big deal just dident see it at first. Doesn't seem to be anything related to air intake, the filters like brand new and all the plumbing seems to be fine the connection is clean. I'm thinking I'm gonna change the rest of my plug wires next two are new the rest are original. Also does any one know how to cut the power to the electric seat belts they don't work as someone has messed with the ignition but the passenger one still has power and it makes a weird noise and I can't find a fuse for it. I just want to cut power to it till I get a new ignition installed. Link to comment Share on other sites More sharing options...
