Hello, I have a 92 Jeep Cherokee Laredo, I recently have put a used engine inside that has about 70,000 miles on it and been having a problem with the whole vehicle randomly stalling when Accelerating or braking or idling, also it surges randomly. Another problem I have found is that sometimes it doesn't want to take any gas while driving on the highway and I hear a almost clicking sound. I recently replaced the fuel regulator, fuel filter, fuel pump, water pump and dont know if it may be the Mass Airflow Sensor or what. I need some advice on what may fix the problem.
My car has 256000 miles.
My car has an automatic transmission.
