My daughter bought a 1979 Volvo 245 wagon six months ago. It has 200,000 miles but is in overall amazing condition. However, recently the car began to briefly stall. This became worse over time. I added injection cleaner to the gas tank. Changed the fuel filter under the hood. Still had same problem. I then opened the air cleaner and noticed oil residue. Oil in air tube. Oil residue in rubber base (balloon thing) that attaches to the hose running to the air filter. Cleaned air tube and balloon base. Also replaced the flam trap as it most likely was bad resulting in too much crank case pressure hence the oil being where it shouldn't. Put it all back together. Still crap! Took hose off air filter and sprayed carb cleaner in. Purred like a kitten - for three seconds! Ran car for 20 Minutes. It idled horribly but I would spray the cleaner and it would purr again-briefly. I checked for pressure on the back side of the fuel filter I installed. I backed off the fitting slightly and gas shot across my garage. Fuel pump works fine I think.

By the way I noticed the timing belt has a sticker that says it was changed at 197,400 miles....... dated April of 2004. It must have set for 9 years without being driven?

I am not a mechanic. Just a dad trying to help his daughter. Any ideas anyone????
