Engine Performance problem
1993 Mazda 323 4 cyl Front Wheel Drive Manual 100k k miles

Hi,
I tuned up the car a month ago with good plugs, cap and rotor (haven't changed the wires). The car was running well. we took it skiing last weekend and left it outside overnight. It was very cold. since then, the car doesn't idle right (seems like one of the cylinders is not working right). the rpm fluctuates when idle and the car has less power. at the same time the exhaust pipe got a hole in it and is making noise (although I don't think that is related, take note for what it's worht).
any ideas are appreciated.
thanks

I would suggestion changing the sparks plut wire with good wires. With the engine off, I would suggest removing one spark plug wire at a time, replacing it with a new wire until you have done all wires and the coil wire. It could have got so cold that the gas in the tank started to gel. Have you tried draining the fuel tank and replacing the fuel with new fuel. You may want to change the fuel filter. (when it get so cold the gas will gel.)
