OK I finally checked why my CEL came on again figuring it was the same P0403 that I have been getting the last 6 months, but instead a p0304 came up. I have not noticed the car running too terrible lately, but I have run it low on gas a couple of times but not empty. I did a search and found some info, but could some one tell me which cylinder is #4? I have a 2.5 v6 ATX and replaced the plugs and wires last year. Also could some one tell me where I can find info on gutting my precats as it seems to be a popular thing to do when the dreaded p0430 code comes up which has happened alot in January through march, but has not come back this summer.
Thanks
