Mazda Millenia 1999 model. Check engine light is on and mechanic says EVAC problem. He checked the car and saw no visible problem with the EVAC wires that connect the gas tank to the engine. He now wants to do a smoke pressure test on the system. Is it safe to drive the car in these conditions? Should I replace any other thing. I was earlier putting regular fuel, now shifted to Premium.

The EVAP system is not a safety issue, but it must be repaired for proper operation and emissions. It could just e a loose fuel cap, or it could be the PURGE/DIVERT valve, or a vacuum line somewhere in the frame rail.
The smoke test is the correct way to go if there is no other failure noted or observed.
This is something you won't have the equipment to perform.
Good Luck

Whatever is causing the out of specifications signal to go to the computer needs to be addressed. It could be as simple as the fuel cap gasket is bad and allowing air to leak past, or the cap is loose. Ask the mechanic what needs to be done. Could also be the EGR valve sticking.
