Question 95 impreza 1.8L--randomly hard starting, stalls occassionally

i just picked up a 95 impreza wagon L, 1.8L,, as a winter college commuter car. I know i'm a newbie on here but i'd still appreciate it if you guys maybe had any insight into my current problem.
for the past week or two, the car is very hard starting ocassionally, sometimes after its been driven, then turned off, then attempted to start say 20, 40, however minutes later (i.e. when hot or warm, after a drive, not cold usually) eventually it will start but it takes a while,...i dont know a whole hell of a lot, just a little stuff...so i checked spark, it was getting spark, looked fine, heard the fuel pump turn on, etc...i really dont know what else to check....i guess illl look at the fuel filter and stuff liek that...
ALSO, the car stalls at stoplights sometimes, the idle is around maybe 600 rpms, probably where it should be, but just once in a while it falls off and stalls at stoplights and stuff..... WHAT do you guys think...a friend who owned a wag with the same problem said he troubleshot the issue for months, finally fixing it by replacing the camshaft pos. sensor, and the crankshaft pos. sensor.....but these are like 60 bucks each...which is fine if it fixes the problem.....
Id just like any help you guys could give me....
ALSO if anyone knows where i might find exploded views of the 93+ wagon impreza that'd be great...or anyting related to this problem, im sure somebody out here can help me hopefully...

oh yea, and the gas gauge doesnt work properly either,...must be the sending unit right? could this be related to the starting problem, im assuming no way but it is near the fuel pump....hmmmm im lost guys please help...thanks....

A 95 should have the flashing codes. Do you have a Check Engine light right now?

Replace your starter and check your vacuum lines. Check the air filter for oil spots...If you find any, then you've got a leak somewhere so check your connections. Clean your throttle body as well (pull plastic air intake off and spray TB Cleaner in it). That should help out.

I'm guessing your CE Light is on for one or more of the following: Bad O2 sensor, Cylinder misfire, MAF Sensor. When you turn the key halfway the CEL should flash. 2 long blinks, and 3 short blinks is "23" for example. Grab a Chilton's manual or search for code descriptions here.

Cheers and enjoy the scoob!

It's funny you mention this. I was JUST going through the same problem with my 2.2ltr 1997 Impreza wagon. I JUST got it to run right today and the car is with me right now at work. I hope it stays this way. Here's what I did.

I had previously ordered a new fuel filter and I installed it earlier today. The car still did that 600rpm idle then stall at the stop light. I checked my vacuum hoses, battery voltage, coolant level, etc, and everything seemed ok. I did two more things and all of it stopped.

1: I purchased some fuel injector cleaner and put it in. It costs $7-$8 a bottle. Get the one that you only have to use twice a year NOT the one you have to put in every gas tank. This is important!

2: Check your battery terminal. Clean them with a terminal brush, apply dielectric grease (if you like for protection) and MAKE SURE the terminals are tight and snug.

I didn't question why the terminals being loose could affect my idle and such. The 'car dying at stop lights sometimes or after warming up' syndrome had stopped. I drove around the neighborhood and to different stores earlier and it didn't do it. Even when I used to come to work and stop, it would act up starting to die, catch itself,...idle...start to die, catch itsel...oops...die. Today when I got here at work, I let it idle for a good 1 1/2 minutes and it held rock solid at 600rpm. No wavering, no dieing, no drama.

These are two cheap fixes that may help you. After that, go for the bigger fish. Good luck!

Oh BTW: I never had a CE light at any time or else, I'd tell you what code followed the 'sudden death syndrome'.

It may also be due for a tuneup. Plugs (NGK copper) and ignition wires (I use OEM).

I agree with the FI cleaner, I use it every 6 months and have not had issues. My car has over 133,000 miles on it and I used FI cleaner on all my injected cars.
