Report A Problem

my old cat gave out and I didn't have any power going up hill and nothing. So we rimmed out the cat which is the honey combs inside and I sounded better but there no oxygen being sensed so my check engine light is on. Some and my friend decided to put on a new cat and new exhaust manifolds. It was successful but the next day I woke up to go to school I didn't drive not even a 1/4 mile on my way and my truck had no power. I pulled over and look...

I replaced the starter onmy truck 99 dodge ram 1500 , 8 cylinders, it starts but wont stay started when i take my foot off the pedal it dies, charged battery, new gas as it sat 2 months. please help . i was told it could be fuel pump filter? Idol control valve, or fuel pump itself i need help oh and ck fuses in which i havent done yet

On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.

The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the "OK to start" signal.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

Some models could have a severe drift or pull to one side when the brakes were applied. If this is not caused by a dragging brake caliper, there is a service bulletin describing the step-by-step diagnosis and many possible solutions. Our technicians note the most common solutions are performing a four wheel alignment, checking torque on suspension components, installing shims between the wheels and hubs, and replacing the suspension arms.

If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.

Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.

shut off, next morning wouldn't start. checked spark plug-dry and okay. pulled timing chain, all okay. checked fuses all look okay. hear fuel pump when i turn key on. starting fluid made no difference. acts like it wants to start but won't. put in new battery.

immediately following rear brake shoe replacement I noticed a delay in abs action following hard braking pressure. The delay is about 1 second during which there seems no braking at all, this after the brake initially grip, then seem to relax before abs kicks in. It is scary


A loud buzzing or whining when the transmission is in reverse may be caused by a regulator valve in the transmission valve body. A revised valve was released that does not resonate. Careful diagnosis should be performed because other causes can create the noise.

Installing a foam pad between the inner door panel and the door can repair a buzzing caused by the door speaker.

One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
