2012 Chevrolet Impala engine problems

“I have about 08/1825 had the throttle body replaced on my vehicle which assisted with the problem temporarily. Then the problem started again 09/20/25 the car act like it’s stalling while driving and can’t see what hear the vehicle is in. The car is not getting any signal to the engine as I have been advised the TCM is faulty. There was a code of U0101.”

“I have trouble codes that occasionally come up even after vehicle has been serviced. The vehicle used to drive fine. Now it started miss firing. I was told the problem was coming from the engine compartment/sensors. An OBDII diagnosis detects a problem with B Camshaft Position Timing Over Advanced or System Performance Bank 2 (p0024). I fear that without the fix, the miss firing can cause an accident. The engine light is illuminated when this happens.”

“I put my car in reverse and the car turned off and have turn back on. When I try to start it, I don’t hear any fix or crank. Before this happened, my car was slow to change gear or it would will change so fast that my car will lose control and I did not feel safe at all.”
