Hello all... just bougt my first VOLVO. It's a 1994 940 turbo wagon with 141,000 mi. on it.Few specs. so far...rebuilt turbo, intercooler, head, timing belt, plugs,wires,belts,brakes,tires,really good shape,with the exception of needing a driver's door, due to snowbank mishap by P.O...what do look for for problem areas, as well as performance for the 2.3 lt. turbo engine?Thanks in advance!!!
