Well, that wasn't it because Last Monday night at dinner, my daughter reported that the Check Engine light was back on.

So I connected my scanner to it yesterday and found the codes mentioned in my previous post: P0234 turbo overboost, P0171 Bank 1 system too lean, and P0101 mass or volume air flow A circuit range/performance.

I cleaned the MAF and, while waiting for it to dry, noticed that a hose below the radiator hose (I believe it is the PCV hose that runs from the grill back to the engine in an S-shape) was broken off at the engine. I got a piece of radiator hose of similar diameter and clamped it in place.

It has been 1 day and, knock wood, so far so good. The car was stalling before when I rapped on and off the accelerator while in park. Now it reverts to a smooth idle.

Does this make sense or am I just going to be disappointed in a day or two when the symptoms reappear?

Thanks!
Gary
