Every year just at the time I need an inspection I get a code P0011. Yes I keep my oil changed, I use synthetic and a high quality filter every 4K miles. Every year I replace the variable VT solenoids to make the P0011/Ck Eng light go away. Is there something I am missing? It has 118K on it timing belt was changed at a dealer at 100K This has been a continuing problem for the last ... roughly 35K. Is there something I'm missing here?
