Need help! Code 232
I've got a check engine light and the code reads 232 / long term fuel mixture too lean at idle. I have also noticed bluish smoke sitting in traffic. Only when it's hot outside but not in the morning when it's cool. No oil or coolant loss, turbo is working and I just tuned it up /New plugs, air filter, cleaned the throttle body and checked the distributor. I just purchased the car, runs fast and hard however after checking today the oil level seems a little high. I plan on changing the oil tomorrow. Any suggestions would help!
Thanks, PaPaT

RE: Need help! Code 232
Hi,
Sorry about the problem.
I would guess that the problem either triggered by a faulty O2 sensor (s) or a faulty injector (s). As to oil burning problem, when was the last time that the PCV system got attention? On 850s, the PCV system uses oil trap and the system is usually better to be replaced as a kit, I would say at every 60,000 miles/6 years or so (may sound overkill to some). Also, plastic/rubber vacuum lines are known to go bad on these cars so visually inspect them.
As to the oil level increase, if the coolant level has not changed, see if you can smell for fuel in the oil. If the head gasket is fine, there may be an injector that is stuck partially open and may be allowing some fuel todrip into the combustion chamber when the engine is not running. Should you decide to inspect each injector, you may have to replace the sealing ring/O-ring once an injector is removed.
As a temporary & cheap solution, I would put a large bottle of Techron fuel system cleaner and try using full synthetic 10W-30 oil. If none of these works, you may want to have each cylinder compression tested, or remove each spark plug for some malfunction indications (you have to remove spark plugs to do the compression test anyway).
Wait till other members come in for other possible solutions. There are quite a few experts in the 850 forum.
