Re: Think we've got the hang of this
Not related to the MAF problem, and not entirely sure if this is what you mean by 'delayed acceleration', but:
I had a problem where I pressed the accelerator and nothing much happened for 2-3 seconds, after which it was fine as long as I kept a steady throttle or kept accelerating. If I backed off and re-accelerated, it was the same 2-3 seconds of nothing, followed by working normally.
This was different behaviour to the intermittently sluggish throttle response I had when I had a MAF problem.
It turned out to be a bad connection on the throttle pot, which I guess could be corrosion?
