Reduced engine power

Reduced engine power indicator comes on. Car loses power
CommenterSeveral issues
Chevrolet Impala 2013 Lt 180000 km
First started with sluggish acceleration. And a dead battery. Fixed the battery and alternator issue. Car still sluggish also jerking when I’d accelerate. I’d let off the gas and press again and it stopped. Until i had to stop and start again. Ran down all leads from everywhere. Throttle body, changed, battery current sensor changed. Ultimately I’ve changed almost everything on my car. Still had the sluggish and jerking. Someone suggested my fuel pressure regulator or injector. Changed both of them. Now my car misfires and idles so badly it barely runs. Barely starts. Has gas dumping into the… Lire en entier

Based on what you’ve described, it sounds like your Impala is currently running in limp mode, which is the car’s way of protecting itself when the engine senses a serious problem. The symptoms you’re seeing — jerking, hesitation, poor acceleration, and difficulty idling — are classic signs. Right now, the most likely cause is an injector that is stuck open or not installed correctly, which is causing too much fuel to enter the engine. This over-fueling is flooding the spark plugs, making the engine misfire, smoke, and even smell of gasoline, and it can also affect the oil. Once this fuel issue is resolved, the limp mode should clear and the engine should run normally again. The radio not working is probably just a blown fuse or ground issue from the earlier battery and alternator work and is unrelated to the engine problem.

Afm. Caught between modes. Turn off. Afm. With the obd plug it you can find on Amazon.
Tcm acting up you might will need a trans rebuild
What you've already had a transmission rebuild and it still shudder?
I have almost exactly the same mileage and having the same issue. It does shift fine in manual mode though

CommenterJerking motion
Chevrolet Impala 2014 impala eco model 135000 km
mainly when im decelerating car drops gears fast depending on how much pressure is applied to the break and will jerk 5 times in place if im slowing down (not stopping) and then applying the gas to accelerate (like it can't decide if it wants to auto stop or turn on)... will also auto apply breaks and turn itself off if im going 1mph and break calipers will open up if it turns back on from an auto stop

CommenterActs like it wants to fall on its face when in gear
Chevrolet Impala 2004 3.6 310000 km
Unit has had new plugs and wires, stutters at the bottom end when accelerated then clears out. But acts like it wants to fall on its face when in gear.
It says on dash service traction control
Chevrolet Impala 2008 3500 v6 ls 187100087 km
And when I put it in gear it won't go , when I give it gas it just puts the rpm high but the car won't move. But on the other hand you give me a push then it will move but it takes it a few minutes of me giving the gas pedal down then t will shift into gear

Des problèmes avec ta Impala ? Partage-les
Slowly for a four count Press gas pedal down and let back up
Turn key to off then start car
If that doesnt work you may need a new Throttle Position Sensor
