SOURCE: 2004 subaru forester, 99,000 miles. Check engine

Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

2010 subaru forester engine cuts out

consider this
when at the stop lights , you will have your foot on the brake as it will still be in drive or in gear and you don't want the car to move
a simple test is to apply the hand brake to stop the car and don't touch the foot brake
if it idles ok but cuts out when you apply the foot brake , replace the brake booster as it has a vacuum leak that is causing the problem
you can do this test in the garage by starting in neutral and allowing the engine to idle , then apply the foot brake
iof it dies it is the booster

Engine bogs when turning sharp

Check vacuum hoses for leaks, cracks an make sure old hoses are not sucking shut , if check engine light is on it could be a map idle sensor, change spark plugs an clean air filter. Most power loss issues come from electrical issues.

Bogging down

Don't waste money on sensors, If it is electrical the check engine light will be on, In which case use a scanner to determine the problem, If no code it is most likely fuel related. Also check vacuum lines.

I have a 1999 honda accord when i mash the gas it bogs down and at idel it speeds up and slows down by it self in park could my calantic converter be stoped up has no power going up a hill but runs good if...

is the check engine light on, keyon and goes out running
yes, its on running ! then scan it. do not skip this...

no need to guess at all, there are simple cheap test, for all failures
forget idle, idle is the lasting that will work with a ratty running engine.
Bogs, not misfire, (shakes for misfire) is lean burning.
if feels like your are pulling a 5000 trailer of lead.
a long hard smooth bog, not transitory.
im sure you did a tune up and sparks are not 15 years old. huh?
possible causes ( you never said what engine in car.? there are many)
1: low fuel pressure.
2: MAF is dirty (got a maf) or if a MAP EFI , the map vacuum cant reach the mAP, for clogging or it leaks reasons, (hoses?)
3: if MAF system , any air leaks will cause bogs.
called unmetered air, and air cant burn, the ECU must see all air
to add fuel correctly. (the 02 sensor corrects for small intake leaks)
id bet your 02 is not even on online at all. do to gross fueling issues.

this is the basics, good engine,good spark good fueling.
we do simple tests to find this.
if you want to test, say so and engine spec, and we can.

what engine, this fact tell me what EFI system you have.
and i can not fix cars with unknown EFI.
a short list. more world wide, why not say country.?
2.0L F20B5 I4 147 hp (110 kW)
2.3L F23A1 I4 150 hp (112 kW)
2.3L F23A4 I4 148 hp (110 kW)
2.3L F23A5 I4 135 hp (101 kW)
3.0L J30A1 V6 200 hp (150 kW)

the car is sold all over the world, where are you?
only 2 posts now in 6000 post told this BIG secret.... funny that.....

I have a f250 97 7.3 L when I give it gas I can

use a propane tourch dont light it start the truck
open the hood
slowely move the torch arround the top of the motor
as you hit the vac leak the engine will start to speed up since it is getting propane and reg fuel
the closer you get to the leak the faster the motor will go
and wala you found the broken or disconected hose

Check engine light comes on and goes...and no boost on turbo

all turbo vehicles can only make boost if induction system is sealed,at this stage rather than looking for a fault with actuator controls,i would check to see if all ducting(piping) is secure.from airfilter,intercooler,turbo etc to engine,just check that there are no leaks,if there are any loose,revving it on the spot to cut in turbo should cause a loud rushing of air.if this is all ok then we need to further.

Check engine light and intermittent bucking

You might get lucky here. Go out and open the hood and start the engine when it's dark. See if you can see sparks jumping around the spark plug wires. That will tell you for sure. Otherwise, my first choice would be to put on new plug wires of the highest quality you can find. I've seen this type of problem before, and it can be made worse if the boots on the wires are not clean or too much grease was used at the factory. The solution was to clean everything and replace the wires and spark plugs because carbon tracks have been created that can't be easily (if at all) cleaned from the spark plug insulators. The coil towers will probably be okay if you clean them well.
