If you smell antifreeze inside of your truck then it may indeed be the heater core. Most of the time the passenger side floor will also get wet from antifreeze if there is a leak in the core. A leak...
Hello. If there is a misfire in multiple cylinders of the engine, this will cause the Check Engine Light to come on. However, there are a lot of other reasons that the Check Engine Light could be on. It is...
Hello. The P0174 code deals with the truck running lean. That means that the PCM is restricting fuel to the injectors. This is usually caused by a vacuum leak in the engine. There could be a leaking intake gasket, or...
Hello. There could be a problem with the throttle position sensor or the idle air control valve. Both of these sensors help control proper air-fuel mixture and engine idle. Sometimes carbon builds up and clogs the idle air control valve...
Hello. It sounds like the transfer case is going bad causing the thumping noise you are hearing. The transfer case transfers power to the front wheels so that all four tires are working during four-wheel drive. If the transfer case...
Hello. This sounds like you have a lean running engine. This can be from carbon build up on the valves and dirty or clogged injectors. Have the combustion chamber and injectors cleaned. Then see if the engine runs better. If...
I would recommend checking/testing the O2 sensor and the MAF (Mass Air Flow) sensor. When either of these two sensors are not working properly, as you may know, they will send inaccurate signals to the ECM which will then, in...
Check the transmission fluid level. Proper checking instructions vary vehicle to vehicle but it's usually imprinted on the transmission fluid dipstick. Typical instructions will require you to check it while in Park, hot engine, and on level ground. If it...
I recommend having a mechanic come and look at the vehicle to check for vacuum leaks or coil problems. You may need to replace the coil pack and ignition module. These older engines may not register misfires as well as...
When it comes to across-the-board codes being set such as this, it is usually a result of something "upstream" creating the condition to set all these codes. For instance, it is rare for both O2 sensors to fail at exactly...
You need to check the charging system to make sure the voltage output is not over about 13.7 volts. If it is then have charging system checked. The fog lights and daytime running lights are on different circuits and should...
Hi there. Shaking at speeds over 40 mph is often related to tires that may be out of balance, low on air, potentially a badly aligned front end or failing suspension components or ball joints. When suspension components are not...
