Does anyone elses car feel abit sluggish from 2nd gear on? 1st gear pulls pretty good, but when I get to 2nd, I step on it and it doesn't really accelerate too quick. I am thinking it might be my stillen popcharger and I am losing some low end. I could definitely feel more acceleration with the stock box. Do you guys have any ideas. Maybe it could be soemthing else like spark plugs, knock sensor, fuel filter?? Also how would you check if the spark plugs, ks were bad? Thanks guys.

 

Y pipe

 

Definitely, your Y-ipie is clogged with 2 pre-cats. You need to have that taken care of.


Seriously, change your fuel filter first.

 

if it feels more sluggish than before, then the ypipe isn't the issue.
it will give you more power obviously, but something else is eating power.

second gear should pull hard
i'd check out the knock sensor
if you feel vibrations or hesitations (engine hiccups) then its a misfire issue (plugs, coils)
also clean out your throttle body.

 

my car is also starting to fell more slugish, could my knock sencor be messed up with no check engine light?

 

Thanks guys for all the help. I also have no cel but i'm going to check the knock sensor and all the other suggestions out.
