Angry Damn car is stalling and hard to start sometimes!

Since I've had my 95 Impreza L series 1.8l it has been giving me problems. I try to take suggestions from everyone and I have changed a lot of parts (listed below) which were recommended to fix the prob. Here are the parts I've changed:
Plugs (bosch Plat +4)
Plug Wires
Belts
Coil
Fuel Filter
Air Filter

I took the car to Precision Tune to have them Diagnose the prob they told me to replace the coil, plug wires, and plugs (hence the new parts in list). Now $90 poorer not including the parts (I was going to get them anyway) I'm still having problems. Starter sounds strong, I seem to have decent voltage. Car dies while idling and is really moody when starting while warm (not all the way warmed up, just a little warm). Any suggestions of what the problem could be would be much appreciated, I'm baffled

Thanks, George

just a quick check on your charging systems....if you have a voltmeter, go measure the voltage w/the car idling.....it should be in the mid 14's....also, check for any slack on all your belts, esp. the alternator belt......

this is just to eliminate some basic obvious......btw, your belts should not have more then a 1 in. play

If your car is dying while idling and you've already replaced all of that, try replacing the idle air control valve.

Default vacuum leak

First of all, Bosch is wrong for this car. Use NGK.

It really sounds like you have a vacuum leak. Check for worn, damaged or missing vacuum hoses. Check that everything past the air mass meter is tight and has no cracks. Check the intake manifold gasket. Does your check engine light illuminate?

Thanks all for the help, I'll give those suggestions a shot this weekend. I would have gotten NGK Platinums but the Pep Boys I went to didn't have any, and I didn't think it was a big deal.

Once again thanks,
George

Default NGK copper

You can use NGK copper plugs in your engine. They are the best plugs in the world. Use platinums only if you need extended change intervals. Otherwise coppers are better. And much cheaper. Call around. Some local stores carry them, some don't. Ask for specific model.

However, since your Bosch plugs are new, they should be fine for about 10k miles. Your problem probably has nothing to do with plugs. Make sure your ignition wires are seated all the way -- they are tough to seat properly on these cars.

You must use NGK copper plugs in your engine. They are the best plugs in the world.

(I changed "can" to "must")

Explain when the car is stalling. Is it at high speed on the highway or when at a stop light or? Does it just cut out suddenly or is it jerking and sputtering?

vvk-
My car is stalling suddenly and while idling or at low RPM <1000. Thanks for the heads up on the NGK Copper.

Default same problems

I have a 1994 L 1.8 AWD as well and My car does the same thing. I have only replaced the plugs so far(ngk's). I'll try some plug wires and see what happens. All my belts seem fine as far as tension. The car has never died but it comes close especially when I first start it up. Just thought I'd let you know your not alone with your problems. I forgot to mention that I did the fuel filter as well. This morning was the coldest so far this winter and my car barely started and sounded abolutely horrible, I thought it was going to die for sure.

Cool

The symptoms you are describing indicate the cam and crank position sensors need replacement. You may have a code stored in the control unit that would confirm this. It was a common problem for mid 90's Impreza's. Subaru has a replacement kit with both sensors-I believe the kit costs about $43.00. The symptoms usually include stalling at idle, and difficult starting after the engine is warmed up,then shut off for 20 minutes or so.
This is an easy repair, and has always cured this condition.
Good Luck-

Default part number?

Would you happen to have the part number for that cam and crank position sensor kit? Or let me know where I can find one. I have been all over the net and can't find it. Last night the car wouldn't start, maybe it's because it was so friggin cold but I'm going to try anything I can this weekend to fix my poor little car.

Unhappy How do I install this sensor kit?

I had the exact same problem you were talking about on this board, so I finally ordered the cam and crankshaft sensor kit from SubaruParts.com. However, I could definitely use some guidance in how to install these sensors. If anyone can help, it would be very appreciated (and sorely needed)!

I got my problem fixed but all I ordered was a cam shaft position sensor. It is actually quite easy to fix, being a mechanical newbie I had no problems. To replace the Cam shaft sensor open the hood and look down directly in front of you on the right (your right, not the engines) of the engine, just behind the fans & radiator. You will see a small part held in with a bolt and with wiring connected to it (the bolt and part are facing the engine). All you have to do is remove the negative terminal on the battery, remove the wiring on the bad sensor, unbolt and take out. Then to replace the sensor just reverse the order of removing it. If you need anymore help a Chiltons manual helped me out a lot, I just wish they made a Haynes manual for Imprezas.

I second this opinion or at least clean the valve and the chamber it goes in with throttle body cleaner. also, clean the throttle body where the butterfy meets the body. there is probably a nice raised ring of carbo built up. Be sure to use throttle body/plate cleaner. Carb & Choke cleaner doesn't cut it.
