codes 172 & 505
98 v70 non turbo
I've just bought the car a couple months ago from a friend. It has 197,000 miles on it. Anyhow, got into this morning and the CEL was on. Took it to the local FLAPS to get the codes read. And this is what they printed out for me.
PO505
001- Vacuum leak on engine
002-Dirty throttle body
003-IAC motor defective
004-Poor electrical connection to the IAC valve
PO172
001-If bank one and two codes set together suspect fuel pressure or MAF
002-02 sensor defective
003-Ignition misfire repair
004Fuel injectore problem
Before I start buying any parts, I'm going to check for the obvious things first, like vacuum leaks. Are there any vacuum hose that are known to go bad. If so, which ones and could you please tell me the location.
Any other suggestions I would appreciate also. This is my first volvo so I don't know awhole lot about them.
Thanks alot,
Curtis
