Q: Rough idle, smoking,CEL on

asked by on

My 2000 celica is smoking, getting misfire codes and idling so low that it dies. Pulled codes (p0300,301,303,304) replaced all plugs and checked coil packs(good). There is lots of smoke and the smell of gas is terrible. I looked around for possible exhaust and air leaks but found none. Please help

My car has 150654 miles.
