#173 of 241 Re: Cuts out intermitently - Fells like running out of fuel [jimbru] by paisan Jan 27, 2008 (8:25 am)
Replying to: jimbru (Jan 27, 2008 8:20 am) Have you replaced your fuel filter yet? It's the black canister on the left side (looking forward) in the engine bay. Should cost about $20 at a local autoparts store. That would be a good start.   -mike Motorsports and Modifications Host
#174 of 241 Engine Coolant Temperature light by sea_note Feb 05, 2008 (3:33 pm)
Hi,   I have 2008 Impreza Wagon and when I start the car in the morning, Engine Coolant Temperature light comes on. After driving for 2 minutes light goes away. I brought car to the dealer but they said it is normal. I think it should be off after 1 - 2 seconds like all other lights. What is your opinion? Thanks.

Replying to: sea_note (Feb 05, 2008 3:33 pm) I get the same blue coolant light in my 08 Impreza 2.5i every mornign I start up. And im not even sure if its the coolant, it may simply be the engine's temp is too low.   We've had below zero temps here in the Chicago area, and that light comes on everymorning. Even if the engines is off for at least an hour in freezing temps and you start again, the temp drops enough to turn that light back on.   I believe it simply lets you know that the temp has not reached its ideal value in order to get the best performance/efficiency/mileage/etc from you engine.   Your best bet is to just wait the 2-4 mins it takes to warm up your engine enough to turn the light off.

Replying to: aaman1 (Feb 08, 2008 12:35 pm) If I have understood other posts correctly, the Impreza does not have a temperature gauge in the '08, it only has the "dummy light." If the coolant is below operating temp, the blue light is on. If it is above normal operating temp, a red light will illuminate. On my car (08 Outback), there is a temp gauge and it takes about 3-4 miles for it to get to full operating temperatures at -20 to -40F. So, at zero, it will probably be on for a couple minutes or more. At room temperature, it might be as short as 30 seconds.   In short, this operation is normal. I would think your owner manual should explain the normal function. Replies to this message: paisan (Feb 08, 2008 5:48 pm)

Replying to: xwesx (Feb 08, 2008 4:50 pm) Yup, even the gauges in todays cars are generally idiot lights. There may be a physical gauge there, but it really only has 3 positions...   -mike Motorsports and Modifications Host
#179 of 241 Backup Lights NW on 1997 Subaru Impreza wagon by tuttt Feb 21, 2008 (3:39 pm)
My backup lights are not working. I have concluded that it is the switch since I can make them come one sporadically by wiggling the shifter.   Does anyone know where the backup light switch is located on a 1997 Subaru Impreza Wagon with manual transmission?   My car has State inspection coming up next month and I don't want to have to pay a mechanic big $$$ to fix it. If I can find it, I can fix it   Thanks!!!

i just bought a 94 impreza i really like this car but the check eng light comes on after about 15 minutes of warmup time and 30 to 40 minutes of driving then it runs rough and it starts to burn gas i get good milage when light is out and bad when on could it be the o2 senser or map Replies to this message: scott011085 (Feb 26, 2008 7:03 am) jimv1125 (Mar 03, 2008 4:11 pm) paisan (Feb 26, 2008 4:59 pm) jimv1125 (Mar 03, 2008 4:12 pm)

Replying to: jimv1125 (Feb 25, 2008 4:24 pm) I'd suggest taking your car to a car parts store that will read OBD codes and determine precisely what your problem is. Although it sounds to me like a faulting knock sensor (I had similar problems on a 2000 impreza - would have check engine light on some days, off others - car idled/ran rough when it was on). I ended up moving the knock sensor to a different thread about 2 inches away and this solved my problem. You could try running a higher octane fuel too - if your check engine light doesn't come on, then it's most likely a knock sensor issue. Replies to this message: jimv1125 (Mar 03, 2008 4:11 pm)
