Q: Car Shaking and sometimes shutting off when accelerated

asked by on October 01, 2016

Recently I have encountered an issue. Whenever I start my car up it shakes very vigorously; in addition, whenever I try to accelerate the RPMs drop and it struggles to get up to speed, and occasionally it shuts off when I come to a stop and attempt to accelerate. When we first purchased the vehicle we replaced the belts thermostat water pump gave it an oil change. My thoughts are that it is the camshaft position sensor.

We also have a OBDII scanner and the following codes were present: 7B [123] signal, characteristic map cooling, short circuit to positive F1 [241] misfire, cylinder4, misfiring during warmup, worsening emissions (misfire CARB_B1) BE [190] Data-filing differnece to central light module 1E [030] AUC Heating

We were also curious of the possiblity that the temperature sensor needs replaced, but we doubt it because the temperature in the car always stays consistenly in the middle. Could it be a bad coil?

My car has 2500000 miles.
My car has an automatic transmission.
