Have a 2001 V70 T5. Changed timing belt last summer. About 200 miles later, the P0014, B camshaft position - Timing code came up. Car drove like it always did, so I didn't worry about it (This was at 225k miles). I did replace the Exhaust VVT.
Now, my girlfriend has a 2001 S60 T5. Her car always seemed much faster than mine, AND I had the IPD ECU update. I figured the V70 just has more miles and thats the way it is.
Fast forward to last weekend. Ignition coil went bad, so I replaced it and checked the spark plug. It was pitted, so I decided that I'll replace them all.
Now, this is whats weird. I went to replace the spark plugs, and ALL 5 of them were loose.(Even the one I checked, and I know I had it real tight) Every one I could hand loosen. Now I have a boost gauge, and my vacuum was about -20psi and would boost to 15ish psi. Never thought anything of it. I replaced all plugs, and made sure they were tight (touch, not torque wrench)
Car Runs so much better now, AND now my P0014 Code has gone! I understand loose/pitted plugs causing boosting lag, rough idle and bad fuel economy, but the P0014 Code and Just after a timing belt change??
Idea's/thoughts?
