The ABS and traction control are part of the same system. The electronic brake control module (EBCM) receives input from the wheel speed sensors, as well as other vehicle sensors. It then uses this information to apply the brakes and...

This code is a sign that the engine did not get to operating temperature in a specified amount of time and the computer turns on the Check Engine Light. The most common problem is that the engine thermostat is partly...

For a more complete answer I would need a bit more information. Various components of the car can cause a difficult start up and not actually trigger a check engine light. The fuel pump, spark plugs, starter and Crank position...

Hello. It sounds like there may be a loose or disconnected vacuum hose (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-vacuum-hose-s). The upper or lower intake gasket could be leaking as well. There is also a possibility that the mass airflow (MAF) sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-mass-airflow-sensor), idle air control...

Hello. If you continue to get code P0135 (https://www.yourmechanic.com/article/p0135-obd-ii-trouble-code-o2-sensor-heater-circuit-malfunction-bank-1-sensor-1-by-jay-safford) even after you have replaced the sensor then you have a problem in the harness or problem in the ECM circuit. Check and follow the O2 sensor harness for the passenger...

Hello. First of all, rotating the engine counterclockwise could very well cause the engine to "jump time", and cause engine damage. The timing chain tensioner is not designed for this pressure, and can allow the timing chain to jump one...

There are a few common reasons for a vehicle to stall (https://www.yourmechanic.com/services/car-is-stalling-inspection). The most common causes are a clogged fuel filter, a failing fuel pump, vacuum leaks, or failing sensors. Some diagnostic testing will be necessary to determine where the...
