I installed a precision muffler axle back exhaust about 3 weeks ago.

Ever since then my engine is louder and vibrates. It gets worse at idle. I can feel small virbations from steering wheel.

Is this normal? because i feel like i'm driving a 20 year old car

Last night, I changed my steering fluid and reset the ECU. While i let me car run for about 5 mins, the intake started to tick by the MAF sensor. it never did that before.

Is that normal?

thanks guys!

 

Try takeing your maf sensor out and cleaning it. I was haveing the same problem just the other day, after i cleaned it with a Q tip and some alcohol the idle smoothed out big time. It also made my exhaust sound a little les raspy. I also have precision muffler axle back, i love it. I also have header and s-pipie thats why i have a little bit of rasp. Hope this helps.
