Engine Belts And Pulleys problems of the 2005 Subaru Baja

Timing belt and associated parts were changed by licensed Subaru mechanic. In the morning when the car was being warmed up, there was a strong smell of gas. Check engine light was on and cruise light was flashing. Drove car to paint shop in san diego and left for five days for painting. Drove the car up to long beach to ship to hawaii. Baja burned 3/4 tank of gas and died off and on. With strong smell of gas. Filled costco gas premium in hawaii and drove home with car dying off and onn with strong smell of gas. In the morning, started cat to warm car up and gas smell was extremely strong and white smoke also appeared off and on. In two days and driving only 54 miles the gas guage was below 1/2 tank. In the process now with another mechanic to repair. Final step will be Subaru dealer. Note: been googling the web and have found that this is a common problem with the 2005 Subaru engine where check engine light goes on and cruise control light flashes. I think this must be a design deficiency on the Subaru engine. I am not the first owner.
