yea it could be a fuel filter, but you feel it chugging down the road... also check your fuel pump relay... make sure it isnt burnt up or melted

The ceramic catalytic convertor is a real bottle neck, it must be removed. The recommended plugs are iridium ones. you will surely see a difference. The fuel filter should be replaced every 50000 KM. Direct K&N admission with cold front air intake. 4 same size tires with regular rotation helps balanced handling. This limits differential rotation and helps smooth running.


He said cutting power, not feeling sluggish or chugging down the road.....

thanks guys


also you might wanna check your vacuum hoses... they can also can contribute to loss of power or chugging... especially when idling

thanks larry will do that, although it idles perfectly, between 0 - 1000rpm
