93 subaru imprezza 1.8 liter is backfiring and sometimes wont accelerate

I bought the car February of this year from my dads close friends shop. He said the lady who owned it said it just wouldn't run anymore and decided to sell it, so they took it and gave it a tune up and oil changed. when I bought it, it didn't have any problems till about 2 months later. now it is backfiring all the time, sometimes its hard to get the car to get up and go to catch up to speed, when going up hills the backfiring and slowness increases making to where most of the time I can barley get the car to hit 25 mph. I know that the car is fuel injected not car-berated so when it kept backfiring I knew something was wrong.

You could have a couple issues, one might be that the timing belts have jumped time. If it's a 1.8L there will be 2 belts, the 2.2L has one belt. I would check timing marks first to see if they are off. 2nd, I would remove the vacuum line from the EGR valve and plug the line. If the car runs better, then you'll need a EGR vacuum solenoid. I hope this info helps!

The problem is uncombusted fuel. Can be caused by timing error (cam or crankshaft sensor), failing spark plugs,a faulty ignition coil (quite common). Go for ignition problems first. Check or change spark plugs and substitute ignition coil (I found one at the wreckers).

SOURCE: subaru vibration

I had similar problem with my '99 outback. Replaced the front half shafts and seemed much better. A few months later seemed to be comming back so replaced the driver side shaft again and the problem disappeared. I had put in rebuilt shafts and the driver side shaft was not rebuilt correctly.

SOURCE: Subaru Legacy 93 automatic transmission is crazy

It sounds like your having some very serious issues.

First off how many miles are on the transmission?
If you have a lot of miles it could be that is it just plain worn out.
When its cold it may work a little better because the fluid is a little thicker and all the parts inside haven't expanded yet(due to heat) allowing them to not "slip" as easily.

I would check your fluid and take a look at it. If its dark and burnt smelling, its time to change it.

If it doesn't smell burned and its a red/oarnge color the fluid is probably fine.

I would then check your fluid level.

If you have to much fluid it can create air bubbles which will cause problems.
If you have to little fluid things won't be lubricated properly and will overheat, and this will also cause problems.

If your fluid level is also fine, then I would check your transmission filter(if equipped). This could be the cause of your problem as well.

If you've made sure you have fresh fluid filled to the correct level and a new transmission filter and it still acts up it is probably just worn out.

Hopefully my tips will get your car going up those hills for a little while longer,

Good Luck,
AadoubleA

SOURCE: car lurches and bucks, rpms erratic on acceleration on hills

You could have any of these problems:
1) vacuum leak- broken air hose or disconnected air hose.
2) water in the gasoline- add a water remover to you gas tank.
3) bad or disconnected spark plug wire(s).
If this were my Forester, I'd take it to a mechanic who has a electronic engine tester..

SOURCE: 2000 Subaru Outback transmission problem

After a good deal of research and several shops suggesting a rebuild of the transmission, I decided to have the trans fluid and filters changed before doing anything. It was a tough call because it could have been a waste of $125. As soon as the spin off filter was removed you could see it was blocked. So the hydraulic pressure in the system was way down, still enough to engage reverse and enough to work all the shifts, but not enough to engage forward without a slight tap on the accelerator.

My Subaru has 240 000 km on it and I suppose the clutch pack rebuild wouldn't hurt, but as it is now it engages quickly and shifts up are noticeably smoother.

May not be the solution for every case, but it solved my situation.

93 honda accord wont start and no spark

If the engine cranks over but wont start, the Hondas in that year range have a pretty good size relay under the drivers side of the dash, its about 1 1/2" by 2 1/2'
you can replace it or just take the cover off and if you look at the solder contacts very closely you will see one or two that have a crack around them.
just put a couple of drops of solder on them to fix the bad connection and you will be on your way. literally takes about 10 minutes start to finish

What year transmissions will fit in a 93 Honda Civic EX 1.6 Liter FWD?

have your transmission rebuilt by accredited professional transmission shops that offer a 12 month warranty
you can get transmission from importers and many from reputable dealers are quality units with low miles
stick with the OEM unit as any variations will cause electronic problems

1995 Subaru Impreza wagon - heater fan

Mine use to work on high only. It was the switch cylinders, something like that. It was an easy fix. Now my blower motor works intermittently. If I kick it, it turns back on. It is located on the passenger side close to the door side directly above your feet (below the jockey box). Kick straight up. If you need to replace it it is also an easy do-it-yourself repair. Make sure before you go out and replace your blower motor that you check your switch. A lot of repair shops will replace the motor w/o checking the switch, you end up paying for 2 repairs. You can make sure it's not the switch by jumping (bypassing) the switch.You apply jumper wires (not cables) directly to the motor, if the motor turns on you know it's the switch.
