the other day i was out for a drive and all at once my car started vibrating and shaking. it only dose it wen im on the gas or sitting at idle. the only time that it dose not shake is wen im off the gas driving. i replace the plug wires and cleaned up the spark plugs and re gaped them. im thinking possible it could be the cat. im thinking that, that could possible of got blocked and is creating to much back pressure. what do u guys think?
