Hi there. In most cases, the lurching problem is due to the forward running clutch pack is not engaging until pressure is high. You will need to have transmission rebuilt to repair the transmission. Since you have an older truck,...

Check for diagnostic trouble codes. If the smoke is blue, oil is getting into the combustion chambers and perhaps the rough running is due to partly fouled plugs. If the smoke is black, the air fuel ratio is way off...

Depending on the symptoms of the vehicle, this may be a transmission problem or a failing axle. Unfortunately, without additional detail as to the specific model of your vehicle, it may be difficult to diagnose without physically inspecting the vehicle....

It is not the axle since the axle on the car is in the rear of the car. You may have heard the brakes or a bearing in the front of the car. Depending on the problem you have, you...

In order to check your fuel economy you will need to fill your fuel tank completely and zero your trip meter and drive vehicle until you use at least a half tank of fuel and then fill the tank and...

Hi there. This vibration on a cold start can be due to low compression. The seal better stops the rough idling when the car warms up and the parts expand. Also there may be an issue with a possible vacuum...

Hello. It sounds like you may have a valve cover leaking. If it leaks, the oil can get on the exhaust and cause smoking, and if it gets on the oxygen sensors, then the car will run like this. The...

This can be caused by either a low battery charge level, or a loose connection in the starter circuit. The battery needs to be fully-charged, and load-tested, to ensure it is not the issue. All starter wires need to be...

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...

Your vehicle has less than 60,000 miles and inasmuch as you mention a possible fault in the engine cooling system, you should check for warranty coverage under Chrysler's 5 year/60,000 miles powertrain warranty. If you are not covered under the...

Hello, and thank you for writing in. This can happen when the battery is low, or has died recently. Although the fuses are good, make sure they are clean and have a solid connection. If these steps do not help,...

Hi there. It sounds like you may have a low fuel pressure concern. A car can idle with low pressure, however when demand is placed on the system it will fail as in your case. The engine is possibly starving...

Hi and thanks for writing to YourMechanic. There are several things to look at. First off, have the coolant tested and make sure it is within spec. If coolant is not mixed at the correct ratio, it can cause the...

Hello. This may be related to what is called a throttle position sensor. This is a small sensor inside the intake system of your car that monitors the position of your foot on the gas pedal and relays this information...

The problem may not be a fuel-related issue but spark or timing. If the engine speed sensor is failing and the computer cannot determine, which cylinder to fire the vehicle will not start. These sensors can often fail intermittently where...

Hi there. There are a few sensors that can cause this as well as some mechanical issues in the transmission. Even though the Check Engine Light is not coming on I always start by checking the computer for any codes....

If you are getting a braking vibration that seems to be present above 40 mph when braking is most likely the front rotors are slightly warped. As the warpage gets worse then the pulsation will be felt at even slower...

The most common causes for this are the ignition lock cylinder or the PassLock sensor for the Vehicle Anti-Theft System. The lock cylinder and/or key may need replacement as well. Try and have this done first. If it fails to...

Hey there. This may suggest that the coolant fan relay switch may not be working properly. When you car is moving down the freeway at higher speeds, the engine gets a lot of cooling assistance just simply from the air...

If you had the distributor out, which I believe is necessary for changing the manifold on that engine, you may not have it installed correctly. The gear is designed such that it can go in any number of positions so...

It has to first be determined if the actual engine temperature is really fluctuating or instead the stalling is just simply a coincidence with a gauge malfunction. A scan tool can measure engine operating temperature. Fuel supply faults are a...
