I have a canadian 2k2 6-speed version, I haven't done the "hesitation fix" (dealer doesn't want to ) ..

My car feels extremely jerky in the lower rpms (especially 2000-3000) and seems to lack power sometimes (on startup on cold days, it feels strong and EVEN oddly enough).

My question: Before all this "hesitation-fix/ecu reprogram" talk, I don't think I ever noticed any of this. However what I HAVE noticed during my last oil change is that my AIR FILTER seems filthy, it's all darkish and crusty looking. On a warmer day, could that be what is causing this jerkiness and/or power loss? I'm at about 20k miles on the odo.

any insight appreciated, thanks.

 

OEM air filters should be replaced every 10k

 

Better yet...spend $40 or so on a K&N filter and you never have to worry about changing it again. You just have to clean and re-oil it from time to time but it's not nearly every 10k, I think I remember reading that it needs to be done every 30-50k. Plus you get increased airflow to the engine...what's not to like?!

 

Thanks guys, I definately WILL change it, I have a FirmFabrications intake that I haven't had time to install yet! -- BUT, do you think that is what has been causing my problems? Would poor airflow cause power loss, jerkiness, etc?

 

most definitely! that and poor gas mileage too!

 

Thanks again! and not coincidentally, i HAVE been getting extremely poor gas mileage, despite being on 'summer gas', and on new summer tires!
