It sounds like it is telling you that the Fuel Cap needs to be Replaced. if the Seal on the Cap is Bad, It will **** air into the Fuel tank.

Fuel pump

Testimonial: "It's the fuel pump indeed. Also the gas tank found to be very dirty. The fuel pump was replaced, fuel system cleaned, now the car runs perfectly."

I have a 1994 1.5 litre Mitsubishi Lancer with a 12 valve engine. Located to the right of the rocker cover is the distributor and coil assembly. I have to replace the coil because the old one died. I can remove everything with ease except for a small spring loaded plate that appears to have been pressed onto the shaft. How can I remove that plate without damaging the shaft so that I can replace the coil?

This problem is usually the result of worn rings but since you already did that, then check the passage that the PCV valve is connected to. It might be clogged, causing a restriction. If that isn't it, then drill a hole at least a quarter inch in size in the top of an old valve cover filler cap and install it. Drive the vehicle and see if things improve. If they do, then check to make sure that you have the correct PCV valve installed.
