New Underdrive pulleys causing missfire
I just installed the Steeda UDP's, and I can feel smoother reving and it pulling a little better. But when I get on the highway (60 mph+) the car will eventually flash the check engine light and lose power.
I got the p0300 and p0304 code, which is a misfire. I have read through other forums, and the problem may be the crank pulley not properly tightened. I am not really sure though..I say this because im not sure if I tightened it properly..if so does anyone has advice how I should do it?
So, has anyone had this problem, and what should I do to fix it?
