2001 neon sohc 38,000 started missing real bad. Dealer plugged in reader and showed #2 & 4 cylinder misfire. Most of the time not bad enough to set off service engine light.
I have done the following. power flushed the injectors, new air filter, new factory plug wires, cooper champion plugs, bottles of injector cleaner and gas drier. It still feels flat till about 2500rpm and seems like it doesn't like the rain, kinda runs weak.
The only thing I know to do next is silicon every wiring connection under the hood. Any Ideas or similar situations??
Thanks

 

Pull you plugs and check them. If you find a bad cyl, check the wires. usually it is either, a plug, wire, or injector on a newer car.
