i have a Injen CAI and a custom exhaust up to the cat, stock cat and y pipe still, my problem is that my car acceleration feels lazy the pick up time is less that before. what is the problem, and how can i fix it.
a friend told me about putting performance spark plugs, will that help?
guys any help would be apprectaied

 

I would use NGK spark plugs, either copper or platinum.

 

Did you check everything to make sure that everything is connected properly, no leak or holes? cause if you got a Injen CAI put on, you should feel some sort of a gain even if you need new sparkies.

If it feels less than before then something must be wrong.

 

its probably your custom exhaust

 

what do u mean, what can it be

 

have you ever changed your knock sensor? or checked for the code?

 

First: please don't post with a subject like "Helppp!!!!!!!!!!!" when your car simply lacks some power.
Before I clicked I thought maybe you ran over your girlfriend or something and wanted us to help hide the body.

Second:
Check for KS Code, replace if necessary - then change spark plugs - use NGK Platinums, replace fuel filter, remove your false sense of urgency, and drive.

lol, u're right, i just needed immediate answers and didn't want to keep bumping it.another friend of mines told me is it becase of the backpressure from the exhaust, he suggested that mabe increasing the piping size might help a little, not alot.

 

any more advice guys?

 

Iam with iansw. do what he said. And performance spark plugs what are those?

Are you talking about the Bosch platinum 4s. Those are pretty good actually.......................................... ........for me to poop on. stick with NGK.
