hey a does anyone have any idea why my car is boging! it a 02 wrx 5 speed. she bogs up with i give it gas though all gears and it does not catch speed. on the freeway she won't go past 40! help!!!!!!!! please! i tired checking my 02 sensor look fine, is their anything else that could be causing the problem.

 

something blocking your exhaust sounds like. you checked your air filter? does it make anymore noise than it usually does? r u getting boost? still riving on the stock clutch? does anything feel off? gotta give a lil more info to go on.

 

no can past 40mph?? No way.. Hmmm no CEL lights come on?? When you mean bogging, you mean the engine sags or hesitates to accelerate. could be air filter, dirty throttle body/fuel system, clogged injectors, dirty fuel filter. Im sure Jon, Justin, or Dave would fill in!!

 

Might be your spark plugs. When is the last time you changed them?

 

vacuum leak somewhere

 

My thoughts as well.

 

Vacuum leak highly possible. Also, check your maf sensor and also the iat by the throttle body (both may need a cleaning, or may have come loose).

 

thanks for the help i going to check my spark plug and my vacuum to see if get any leaks.
