Q: Truck not starting after electrical fire

Hello! There are a few reasons in which a car may experience shaking. However, the most common cases are caused by suspension faults such as bad axles, bent rims, or tire imbalance. I strongly suggest having the suspension inspected (https://www.yourmechanic.com/services/brakes-steering-and-suspension-system-inspection)...

Hi, thanks for writing in. The OBD-II Error Code P-0170 (https://www.yourmechanic.com/article/p0170-obd-ii-trouble-code-fuel-trim-malfunction-bank-1-by-andrew-quinn) indicates that the powertrain control module is detecting a fuel trim that is outside the range of specification set by the vehicle’s manufacturer. This can mean a negative fuel...

It sounds like you've covered the basics. Did the transmission shop check the fluids in the transmission and differentials? Very dirty fluid may contain metal shavings that cause the drivetrain to bind under load. It is not unusual to find...

Hi, thanks for writing in. I would recommend using a high mileage semi-synthetic oil. High mileage oils are designed to remove unwanted deposits created by wear and tear over time. Sometimes, switching to straight synthetic oils (https://www.yourmechanic.com/article/can-you-switch-between-regular-and-synthetic-motor-oil) at high mileage...

Code P0622 relates to the alternator not working properly. This code can sometimes come up when the battery is weak. I would recommend testing the battery first and if it checks out OK, then the problem is likely the alternator...

Hello. I would not recommend changing the water pump unless there is an issue with it. It is common for the water pump to fail, but it does show signs of leakage first. ANy good mechanic can check it to...

Hi there. It is possible that the transmission is not your problem. If the vehicle is hard to accelerate, it could be cause by a fuel system, ignition system or drive train component failure. Due to the fact there are...

The downstream oxygen sensor (post converter) monitors the efficiency of the catalytic converter. If there is no downstream sensor after the second converter then the P0420 code cannot arise from a fault there. Exhaust leaks have to repaired anyway, due...

The check engine may be blinking due to computer sensor or misfire issue. Have the computer scanned to get the failure codes and then have the codes diagnosed. You may have a lean injection system causing misfire when first started...
