Why does my Subaru stutter when I accelerate?

Why does my Subaru stutter when I accelerate?

A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.

Are there any problems with the forester Outback?

While 2000-2003 legacy and Outback models have had problems in that area with a small cap and o-ring being compromised (and shutting cars down completely), the issue has never been reported in 04 . Maybe the Forester Forum would know for certain. You can get the cap and filter on-line, dunno about just the filter.

What causes a 2004 Forester to stutter under load?

Mine flaked out on me without setting a check engine light and was causing all kinds of bucking and hesitation under load. If your car has a MAF sensor the oil from the K&N has worked its way onto the sensor element and “clogged” it. It will need to be cleaned with MAF sensor cleaner and the K&N replaced with a regular paper filter.

What should I do if my forester is sputtering?

You may also need to clean the intake piping and filter box to remove any excess oil to prevent a recurrence. If no MAF sensor, change the spark plugs and wires. Even if you don’t have a CEL on this sounds like typical misfire under load symptoms due to old spark plugs.

What was the hesitation problem on my Subaru Outback?

My hesitation was due to my plug wire on #3 breaking apart after the last spark plug change (I pulled on the proper location of the wires to take the wires off). I changed them in the parking lot of the local Subaru dealership (when I was out of town!). Fixed.

Why does my car stutter when I hit boost?

it sounds like you have a boost leak…. check all of your couplers, and hose clamps… you may not have tightened all of the hose clamps tight enough… ok, if theres no boost leak, try checking the gap on your spark plugs. also if you can, use evoscan and datalog some logs…

Why does my car sputter when I Turn on the engine?

The fuel filter ‘s job is to filter the fuel going to the fuel injectors and then enter the engine. A clogged fuel filter can cause the engine to get too low fuel pressure or cause a clogged fuel injector. Low fuel pressure will cause the engine to run very leanly, and therefore it may cause the engine to sputter.
