When I press the gas pedal all the way, car accelerates slowly until 4000rpm, then remains at that rpm, then no more accel. When I ease up on gas pedal, about halfway, car shifts up (eg 3 to 4) and starts accelerating again. Even when accelerating (gas pressed 1/3-2/3 of the way), power is very low. My friend has the exact same car and it accelerates like a beast compared to my car. The issue does NOT seem to be that the engine is revving but no power is getting to the wheels due to power being lost in the transmission. The engine itself is slow to increase rpm and stops increasing after 4000. Car has had poor mileage for more than a year. I recently changed the fuel filter. Car only had code p0131 for o2 sensor voltage low. I changed sensor and reset computer, now same code is back. O2 sensor code has been in car for more than a year, but I didn't replace sensor until recently. I recently changed spark plugs, and MAF sensor seemed clean and fine. 130000 miles. Automatic transmission.
driving a long and it just stop. no fuel or fire tryed everthing
I have a Pontiac Grand Am with the 3.4 V6 and I recently had to have it towed home because it was juddering violently and seemed quite low on power. Since then, a friend of mine who has worked on cars has checked the codes on it. It registered a "cylinder 5 misfire". We replaced the leads and plugs to no avail. We rented a tool and found that there was (apparently) no coolant in the engine block. That said, the fouled cylinder and at least one other were fouled with coolant. My friend, without having examined any further, thinks it could be a bad valve lifter. I have tentatively arranged to get it towed to a repair shop for further investigation. When presented with the facts I so far have, the guy at the shop thought it could be a bad cylinder coil. However, since I do not want to drive it in its current state, I would likely have to get it towed to the shop. I just wanted to see if any of you think it may be worth trying to fix or if it would be better to scrap it?
