fuel smell out tailpipe

In a 1993 3.1 engine, what could cause a fuel smell coming out the tail pipe? The engine has a steady miss sound at idle, and acceleration its worse until the rpm get up then it takes off smoothly, like when shifting into second gear. The plugs and wires have been replaced, yet the same problem.

Thanks for any help, kinda need this car running.

I would have it checked for codes also; Auto Zone will do it free. Check Engine light ever been on? O2 sensor a possibility, will often cause an over-rich condition when they fail.

yes the check engine light does come on about a minute after the vehicle starts, but will the coil set off the check engine light. Crazy question i am sure, but these elctronic things really throw me. Gotta love the horse and buggy times.

Ignition problems, i.e. coil, dist cap, rotor, plug wires, plugs will not set off the check engine light unless they affect some related item or system. First step - get the codes read and post back here what you find. Is there an Auto Zone in your area?

there are no engine codes, and i have now replaced the wire, since the mis is on cylinder 4 , with no signal to the wire at all but the others are fine, and cylinder one which is on the same coil fires fine, and i have replaced the coil still nothing and have replaced the module, still nothing on 4
