Question about 1993 Subaru Impreza

2 Answers

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).

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,

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.

Why have i lost power after installing a K&N pod filter on my 2008 subaru wrx imprezza

This new filter has probably affected the MAP/MASF sensor because the air flow has been altered . The word performance will be the clue so you may have to find a speed shop with a chassis dyno and have the chip remapped to the filter.

How long does it take to fix the air bags in the air suspension in a lincoln town car

Every repair place you go to, will have different recommendations
for your situation

You have to decide if you want to spend money on a 19 year old

Personally I wouldn't, & I do all my own work & get parts at a discount

Think about your question
How would we on the internet without the car to test,be able
to tell you if it was the compressor,air bag shocks/struts or
compressor,plastic or metal air lines,electrical issues,etc

If your keeping any vehicle,with air suspension, I only have one
recommendation every time I get this question & it applies to
almost new vehicles as well


There are at least 6 big well known brand name companies that
make conventional replacement shocks etc

You remove the air bag deal & replace with a brand new,not
reconditioned,vehicle specific shock complete with the spring
necessary for your vehicle

The how to disable the air compressor,remove or tie up the
air lines & other issues is up to you, or may be in the instructions.

On a 4 year old ford or lincoln you can't afford to have a dealer
try & diagnose those systems,not from what I see on this web site
The dealers can't resolve their own products anymore

My 98caddilac deville keeps running hot,i put thermostate,waterpump i took it to shop they did a pressure test it all check out good . i was told it could be my passenger side fan but i think it should be...

I have a 1997 Cadillac Sedan Deville that did the same thing. I replaced the same things you have replaced on yours. The end result was a blown head gasket which I have found out is very common on older model Cadillacs that we own. After replacing the head gasket (which cost me parts/labor $2,200.00) at a reliable mechanic's shop that I have used for over 20 years, the car does not over heat. When I replaced the head gasket, my Cadillac had 131K. However, I have seen blown head gaskets on Cadillacs (similiar year/model) with as little as 50k at used car dealerships. Cadillacs are terrific vehicles but I've found out that bad head gaskets on older models are common problems. Good Luck...Hope this helps a little. A. Levisy in Virginia
