I researched the posts on this, but most of the diagnosis has revolved around both a 0170 and a 0173 code, indicating a MAF problem. I am showing only a P0170 right bank reading and the check engine light stays on. I opened things up and found a completely decomposed vacuum line (from valve cover to throttle body) which I have replaced. It still takes half pedal to get the car moving, but after that its a rocket ship. With the hose replaced, why do I still have sluggish get up from a stop light? Is it something that must be reset before the on board knows its fixed? Or was the hose just a side trip and the real deal is gonna cost me?

Any thoughts?

Did you try to reset your Check Engine Light by disconnecting the battery for a while? It still could be a MAF problem or was that the only vacuum leak or bad hose you had?

Yep, a few minutes ago I disconnected power, waited two minutes and reconnected. The CEL went away and car idled nicely. Took it for a hard lap around the neighborhood, and A-OK rocket ship action. Get to my stop sign and the engine dies with the ASR light illuminated. ??? Restarted no problem and the CEL "Engine Electronics" light is back on.
