After my car has been running for a while (over an hour), and I approach a steep hill or go to pass another vehicle and the car downshifts, the engine maxes out at 3100 rpm and jutters. Even when I depress the accelerator, the car will not increase speed. This causes the check engine light to come on (P0131). Then when I slow down and come to a stop, the car doesn't idle. It revs up and down, stalls, and dies. I have to put the car in neutral and depress the accelerator and rev up the engine to keep it from dying. I have replaced the oxygen sensor (Bank 1, Sensor 1) and the fuel filter, but the problem persists. Side note: The car temp used to hover around the 25% mark (even with A/C on during summer). Now the temp gets up to the 50% mark when the car slows down, stalls, and dies.
have the same problem?
