My check engine light threw today then cleared, and then threw again so I bought a code reader and it says my 4 cylinder misfired.... Any ideas on what could cause this? I wonder if this is the problem I when I stomp the throttle and it almost feels like it's studdering up to speed? Is turbo lag a studder or just "slow" at low rpm's?

Help!

 

Do you have an aftermarket flywheel?

 

As far as I can tell the car is %100 stock... I bought it from a dealer so who knows really.

 

might wanna bring it back to the dealer to see whats wrong with it.

 

Sometimes I know with lightened flywheels it throws a misfire but not sure what cylinder

 

spark plugs

 

have them check your plugs and packs. But a number of things can cause a misfire.

 

I think that throws a generic misfire, not a specific cylinder, but maybe each car reacts differently.

If the car was purchased recently I'd take it back to the dealership. If you are able to change the plugs yourself I'd do that and then go from there. Or you can just bring it to a local suby shop and have them look at it

 

i had the same problme and i changed my plugs and coil packs and ithe a few days later the code with off again i did have a lightweight flywheel and thats what it was but i found out with another tune that will never happen again but i would take it back to subaru and see what it could be
