Subaru Problems? Ask a Mechanic for Answers ASAP
Hello...welcome and thank you for using Justanswer.
How many miles do you have on this vehicle ?
When was the last time you replaced your plugs ,wires and filters (fuel and air) ?
Do you have the check engine light ON or does it blink when you try to give gas to pick up speed ?
Try to pull a spark plug off to see the condition of them, also ,check for oil in the spark plug wires where they go into the cylinder heads ?
Is the power steering hard to turn ?
Have you check the power steering fluid to see if it is full ?
Do you have any noise when turning the steering wheel ?
Sorry for all the questions , I need to know to give you a better answer.
Let me know.
So the engine starts and runs fine right ?
By any chance ,do you have anyone that can check the fuel trims ? (will need a scanner with data to do so)
Wonder what are the fuel/air mix values.
With the engine running can you wiggle the harness by the Mass air flow sensor to see if it the idle changes or get rough ?
Also ,can you disconnect the battery for a minute and then connect it and try to see if the hesitation goes away?
If no and yes to the questions above my best guess would be a weak up stream O2 sensor.
Hi there ,the mass air flow sensor is mounted on the inlet pipe that goes to the air filter box .
Also it may be a good time to check the timing ,with this mileage is possible that it jumped time.
Hi there... I am glad you have fixed the problem .
On the power steering ,looks like you have a leak somewhere ,pump and the pressure hose are common to bad, just keep you eyes on it .
I really appreciate if you take a few seconds of your time and rate my help ,positive rate really help my performance here at this site.
Thank you very much.
