I have a 96 accord EX 2.2 single overhead vtech. I can drive for 30 to 45 minutes and then the motor starts to bogg down, I can step on the gas and it comes back to full power or just let off the gas for a few seconds it comes back. Since then I have replaced the plugs, wires, cap, rotor, coil, fuel filter and put a cold air intake on. oil smells a little like gas and I get an exuast smell when it happens. WTH?

 

main relay??
fuel pump??

 

bad idle maybe
