Default 1995 Impreza question

Hi!

I have a 1995 Impreza (manufactured in 9/94), 1.8, four-door sedan, with 200K miles. I have a couple of questions.

The check engine is on and there is a noticeable loss of power when going uphill. Also, when going on a flat road, if I press the gas pedal al the way, the car will not respond immediately. The engine seems to be in very good condition. What we have done so far is to change the wires, the spark plugs, the air filter, and the coil, and examine the catalytic converter (it's good). Before replacing the plugs and wires, I had to press the gas slightly when starting the car, but now it seems to start fine. After we replaced the parts, we disconnected the battery for a minute in order to get rid of the check engine light but that didn't happen.

My questions: what do you think is the issue and is there a tool that will read the codes on this vehicle (i didn't see an obd II connector)?

Thanks for your time!

It isn't OBDII.

You'll need to disconnect the battery for more than a minute to reset the ECU. You noticed a lack of power. Can you rev it the full range of the tach? Or is it locked in safe mode?

Sounds like an o2 sensor to me. I would get that code read though. Several indepentant shops will read the code for free. A dealer will charge you for an hour of labor.

Thats what I thought. But I've got a coworket who drives what he swears is a 95 L coupe that he also swears is OBDII. He must be confused.

i have the same car almost and i seem to have a problem every time my radiator fan kicks on. it will run like crap. to reset the computer on that besides disconnecting the battery terminal you can go under your dashboard and find two plugs one is green and slightly large and the other is black and small. plug both of those wires in and start the car it will erase any problems that your car seems to have for the time being. shut down the car unplug the wires and start it up again and your computer should be reset unless it's a permanent problem.. hope i helped you

Hello:
You don"t need a scanner, under the dash near the column there are two green connectors. Plug them together, count the flashes. Do a Google search to get the codes.

Default 1995 Impreza question

Guys,

I have a follow-up.

We took the car to a Subaru dealer. The technician told me he drove the car and monitored the data (he hooked it to a scanner). He said it was driving fine, the 1.8-liter engine should drive like this. But I insisted that it should have more power than that and the Subaru tech ventured a guess that thought the timing may be off a hair. He said the check-engine light didn't have any codes and could not be cleared. He thought it was some sort of electrical issue that triggered the light. Which is possible because when a few days ago I had a new CD player put in, the CD guy told me he got no power to the CD, so he hooked a new wire (coming from the fuse box) to the CD player.... This caused the dim light not to work...

Well, the car needs help (gas) when first starting it in the morning, and it's not becase of the cold weather. Also, as I mentioned in the originaL POST, It doesn't have much power--when I step on the gas, it doesn't produce an immediate accelaration (or even an attempt at accelarating). I think it may be a fuel issue... maybe fuel injectors or the fuel pump.

What do you think? Any opinion is appreciated. What can I do to further diagnose the issue? I will be driving the car across the country so I need it to be dependable. Also, do you think the electrical issue is hard to find and eliminate?

Thanks.

Hi, our 95 impreza (1.8) wagon started showing the same symptoms a week ago after getting its oil changed at Jiffy. Besides changing the oil, they replaced the serpentine belt. They also pulled out the PCV valve and air filter to show me they needed to be replaced. I figured these last two would be easy to replace myself so they put them back in. Next day, the Check Engine light came on though with no noticeable difference in the way it drove. Several days later, it was hard to start. When it did start, it would stay at idle (or almost die) if I stepped on the gas. It eventually starts running normally, but the radiator fan is now running constantly and the CE light is still on. Now hardly knowing anything about this stuff, could it be the PCV valve? I know its not the filter as it's not too bad. The belt they replaced seems to be at the right tension too. Anyway, we've 172K miles on it and it's the first time it has shown any problems.
