I've posted before, and was thinking maybe it was vacuum related, but doesnt seem to be. Im getting a weird condition, the engine starts up fine, stays warm fine, but when it gets hot, sometimes (not always), the engine starts slowing down (at idle). Like we're talking the engine is slowing down,, until it almost just stalls out, but then surges back up to regular rpm, then starts slowing down again, and again... repeats. This has gotten progressively worse. THe other day I was coasting, getting ready for a turn, and no power steering! THe engine had stopped, but it stops so gently, I didnt know.... Any idea? EGR? TPS????
