GM 8-Lug vehicles are known to have a front bushing problem in the lower control arm. To prevent this problem from causing more problems further down the road, the problem should be fixed now. The front bushings work themselves out of the lower control arms. The solution is to press out the front bushing and press it back in from the other direction. Instead of the bushing being pressed in from the front of the truck toward the back, the bushi...

hard starting after several hours and upon start up, engines missfires and runs rich

Possible fuel pump regulator failure under the upper intake leaking fuel directly into the intake system.

You must replace the regulator assembly and possibly the spider( injector cluster) to resolve the problem. Allowing the engine to run like this for an extended period could result in cylinder wall wash down resulting in internal engine damage.

Whining noise 40 mph - 60 mph - louder under load - quiet when coasting. Ring and Pinion going bad

The engine may be hard to start run poorly and/or use to much fuel due to a fuel leak inside the intake manifold plenum. Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak. Removing the "tuning valve" from the upper intake will allow for limited visual inspection without removing the upper intake manifold.

Vehicles using the enhanced vortec V6 engine may be hard to start run poorly and/or use to much fuel due to a fuel leak inside the intake manifold plenum. Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak.

Engine would start then immediately die, after a few attempts the engine would then start and run normally. It was found that when the car died the radio would not be on. Detent had been lost between run and key-on positions of key switch, so the force of the start return spring caused the switch to go to the almost off position, where the engine red light, ecm, etc would come on but not the fuel pump, and radio would be both off.

Last winter I was driving my husband's Cavalier during a rush hour winter snow storm when all the lights went out and the car went dead. I barely made it over to the side of the road without getting hit. It turned out to be a bad alternator. We had just replaced the starter and battery and then this happened with no warning. Very scary. I was told that when we had the starter and battery replaced, the alternator SHOULD have been checked, ...

I have water in fuel, it was not used for a few months, and when I filled it the water in fuel light came on.
I would like to change the fuel filter. Where is it, can I get at it from below, etc Thanks, Jon

The resistor block (located somewhere on the left side behind the interior walls) has failed. Have a replacement from an junkyard vehicle but have not yet put it in.

I had a mysterious leak of coolant. It was winter and I was losing coolant. I could fill the coolant up drive, forever w/heat on and check the coolant and it was fine. I would check the coolant before starting the truck and it would be half empty.
I have the habit of turning everything off in the vehicle before turning off the car, especially in the winter when I know it is hard to start in the AM. I turn off the heat.
The heat control valv...

Noticed white colored goo on oil dipstick during oil addition. Dealer indicated a failed head gasket. Solution is to replace the head gasket. Will also replace the valve cover which the dealer indicates is now a better design than the original cover. Dealer estimate is approx. $1200.

The Chevy Aveo5 Special Value has had problems with the sensors from the day it was driven off the lot. It failed inspections for emissions every time. This time around, it was taken to the dealership for diagnosis. They said it was the electrical wiring harness. It had to be replaced. This car has had nothing but problems from day one. It's at 100,000 miles right now and has had thousands of dollars of repairs and still isn't right.

Engine light come on for a second. Speedometer and tach flickers you can hit brakes it does. Seems like when it shifts or high speeds

ABS light on, book says cheek speed sensor left front wheel, also the brake pedal slowly goes to floor but its not loosing fluid

We had seen problems on these engines when the main timing chain tensioner begins to fail. The engine will make a terrible rattle noise and then gets quiet. If problem is not address promptly, timing chain will skip over the cam gears causing great damage to engine. GM had extended the warranty on these engines up to 100,000 miles, call dealer for more details. Also if engine is over 80,000 miles is a great idea to replace the water pump, it w...
