I ve been noticeing that my car is draging itself around. I dont like it at all. when i press the pedal all the way down the goes ,but at regular driving is getting bad.
Ive change spark plugs
cleaned the TB
changed th fuel filter
just put and intake (which is working fine.)
just did an oil change i always use good stuff.
but i just remember my muffler has 2 little holes could that be the problem.
I hace to fix that anyway , but could it be something else.
any help would be great
thanks

 

Knock sensor, read the FAQ's

 

the intake, when i put in my short ram, i lost a lot of low end power.

 

i changed that too
about 2 months ago
anything else

 

check your MAF,

maybe an o2 is going/gone.

is it at a certain part of the rpm band that you dont feel the power or is it from idle to where ever you dont feel it?
