Q: Changing oil grades without flushing

There is a release mechanism under the hood, but it may be difficult to locate and manipulate. Often, the mechanism needs to be lubricated once it does release. I highly suggest having a trained mechanic, like the ones we have...

Hello. Worn out transmission and motor mounts will cause this as they will be allowed to move while the engine is running. That movement causes the vibration. If they are definitely worn then they should be replaced. The most common...

The code P2187 indicates a lean running situation at idle. More parameters will need to be checked to get to the bottom of this issue. Sometimes false reading from a malfunctioning mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement) may mess with the...

If the heat sensitivity is a good clue, this could well be the ignition control module, which is quite heat sensitive on the big block Chevy's. Would check fuel pressure (while running) as well to make sure you're getting enough...

Your tire pressure light is simply telling you to check the tire pressure. The reason it comes and goes is because the pressure is directly related to the temperature. While you are driving, the temperature fluctuates and the tire pressure...

Hi there - I suspect your vibration behavior (https://www.yourmechanic.com/article/what-causes-a-car-to-shake) is caused by driveshaft problems with one or both of the driveshafts. This may be simply an out-of-balance problem, or a mis-aligned or bent driveshaft issue. You should have eliminated bent...

Hello. This can be caused by a number of things. Most of the time if this only occurs when coming to a stop it is because the computer is not maintaining a high enough idle. This can occur because of...

Hi there. When the codes P0420 (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) and P0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) come up, usually the catalytic converter has failed, but before you determine if you need to replace the catalytic converter, consider checking the following: A damaged or failed oxygen sensor...

The issue is the fuel pump relay on your fuel system. The fuel pump relay is getting hot and shutting off the fuel pump. Then when you shut off the engine and key to the ignition switch, the fuel pump...
