Thank you!
 

I recently purchased my 2003 S-type, V-6, 5 speed manual with 70000 miles. Great car, but I immediately had some issues. The a/c was randomly blowing hot air, I was getting an engine light with a P0174 code, there was an oil leak at the rear of the engine, there was a slight coolant leak, and it needed shocks. I researched this forum and found answers and suggestions for all. I replaced the shocks, DCCV, coolant overflow reservoir, and fuel trim o-rings. Solved all problems except the engine light and P0174 code. I checked all vacuum hoses and connections visibly and by spraying carb cleaning and watching for rpm increase. No success. I read a post that suggested it might be a weak battery. I checked voltage across the battery when engine was off and found 11.9 volts. A little weak, but how could this cause the P0174 (right bank lean) readout? I replaced the battery anyway. Now, I have 12.8 v across the battery. I've driven the car 400 miles and no engine fault lights. Thanks for all of the excellent advice I received on this forum. I really like the car.
