It sounds like you may have a faulty AC Compressor or potentially a leak in the AC lines somewhere. Car air conditioners work on a simple principle of heat transfer, relying on the fact that heat will always transfer from...
Hello, since you have a brake fluid leak, this needs to be repaired to make the car safe to drive. I would recommend not driving the car until this is fixed. You state that you hear something dragging, this should...
Hello. It sounds like the sonar system is malfunctioning and you have some sonar system sensors that are not working properly. The sonar system should be diagnosed so that the proper sensor can be replaced. Once the sonar system has...
You may have a sticking EFI relay in the main fuse box in the engine compartment. This relay if stuck on can keep power to the computer to turn on check engine light. Replace the relay and then retest. ...
There is likely a problem in the fuel, ignition, or air induction systems. When you put the car in drive, you are "loading" the engine and obviously due to some fault the engine lacks sufficient power at that point to...
The stock wheel diameter for this vehicle appears to be 16 inches or, optionally, 17 inches. To return the vehicle to stock, it is best to buy a set of OEM rims from a GM dealer. Aftermarket rims may have...

If you suspect the fuel pump is not pumping enough pressure then you will need to have a fuel pressure test with a fuel gauge to check to see if the pressure is high enough or not. You can have...
The first thing that comes to mind is a crankshaft position sensor. It has a very fine coil of wire that sometimes is affected by the heat of the engine. The common scenario is that the car starts easily, but...
Hi there - some problem codes require a certain number of "drive cycles" before the ECU will turn off a Check Engine problem code, O2 sensors often being one of them. If your truck is running well, ignore the light...
A voltage test will not reveal whether the battery is defective or not. A different test, referred to as a "load test", is required. During these no start incidents, check to see if the engine immobilizer system (security system) is...
Just because the wheel has weights attached to it doesn't mean it is balanced correctly. My guess is that the wheels/tires are out of balance. However, the problem could also be worn steering/suspension parts or tires. A bent rim...
Hey there. The timing belt is designed to last a long time and most vehicles recommend replacement between 60,000 to 120,000 miles. If your vehicle recommends a replacement interval of 90,000 miles then you should have it done at or...

Hello - first task is to retrieve whatever problem codes are tripping the Check Engine light. Most auto parts stores will do that for you for free. Without that info, I suspect you have a weak spark plug or ignition...
Hi Gibran. This is a rather common problem. In most cases, when you have an error code trapped in the ECU, and a repair is made, there are two reasons why the light would continue to trigger. First, you have...
The radiator is part of the engine cooling system and would not typically be inspected or serviced if the passenger compartment air conditioning system is not working. If the car engine is overheating you might inspect the radiator though. If...
Anytime you see a coolant leak under the vehicle you know you have a leak but the location is not known. You will need to have the cooling system pressure tested to see where the leak is coming from. It...
All Wheel Drive (AWD) works in any gear the vehicle is in. There are two types of all-wheel drive: mechanical and electronic. The most common way of creating a capable, mechanical AWD system is by using three differentials. A differential...
Hello. I would have the system scanned for any codes and have them diagnosed to see if they lead to possible cause of the problem. Have the fuel system also checked for any problems when the problem happens to help...
Hi there. Assuming the backfiring was taking place prior to replacing the spark plugs and spark plug wires. This would lead me to believe there is a valve train related issue. Possibly, a broken intake valve spring. This would account...
