Came across this SHO with 165k miles guy had it in garage and hasn’t started it in a year bc of smoking problems. I changed the battery and checked the oil , oil smelt like gasoline and level was really high? So I didn’t take a chance starting it with that oil in it so I changed the oil and added fresh oil. Old oil looked fine just a gasoline smell. I started it up with the new oil and a lot of smoke is coming out exhaust and smelling just like gas. Idle is very rough and it’s missfiring I pulled some codes on it p0354 p0342. So cylinder 2 and 4 is the problems . I’m thinking of just replacing all spark plug and coil. But the guy said he would take 500 for it I’m trying to see if this is something to invest in.

I don’t know a lot about these cars but I’ve admired them from afar. I am buying this as a car for my 17 year old son to drive for about a year and then it will be my spare car. Sticker price is $8995 before trade in. I really like the car but don’t usually go this high mileage. So any tips on things to look for would be helpful.
