hey guys, I have been having an on going issue with hesitation and a rough idle. While sitting at a light my car will randomly kick.. it also has hesitation up to about 25 mph. I am not throwing any codes at all. Ive tried everything. Took it to the dealership too and they couldn't figure it out. I have a K&N cai and a racing beat exhaust. About a year ago I replaced my cat with a straight pipe.. I am wondering if this maybe has something to do with it? Any advice would really help! Thanks

 

You may have a dirty fuel filter. Replace it and then see whats up.

 

replace your spark plugs, coil packs and wires
