It is possible that your Exhaust Gas Recalculation system (EGR) is faulty, and is venting exhaust back into the engine at the wrong time (during idle). There is a Recall for you year and model (T493) relating to a problem...

Hello, thank you for writing in. Vibration and shaking is typically associated with a poor combustion taking place inside of the cylinders. This can be spark, air, or fuel driven. Think of it this way, the vehicle has a constant...

P0172 means too much fuel or, conversely, too little air, is being supplied and thus the air fuel ratio is sub-optimal. Other causes of this code setting, that are not reflected in your list, include a dirty mass air flow...

Hello. From what you describe, it appears that your vehicle may be experiencing electrical issues. If the brake lights are staying on at all times, then the first thing I would do is check the stoplight switch. If it is...

Hi there. This is usually either caused by a bad idle control valve or a vacuum leak. The idle control valve is located near the throttle body. It can also be a dirty throttle body. I usually start by cleaning...

Common causes of no cabin heat include malfunctioning blend door(s) (part of the in-dash ventilation network), a faulty or stuck heater control valve, a plugged heater core, collapsed hoses, and low coolant level. The cost to resolve the problem depends...

It sounds like this is an intermittent issue. These are generally the hardest to diagnose because they are just infrequent enough to not trip the ECU into triggering a code, but they still have a fault somewhere. The most common...

First thing to check is to see if all the corrosion was removed and neutralized on the battery clamp and cable. The have the charging performance tested to see it the alternator is not overcharging and causing the battery to...

Check the lights on the dash and look for the wiring. Follow the wires to where they hook up to and check that component to see if it's working. Most dash lights are hooked into the light switch and on...

Check the transmission fluid level to see if it is full. If the filter was replaced, depending on the type and configuration, the filter could even be banging around. "Clunking" noises are very typical of failed outboard CV axle joints....

Hello, this transmission type has a shift cable that routes from the gear shift to the transmission. The shift cable assembly may be broken causing this issue, this will require an inspection to confirm this. If you'd like, a certified...

The gears in a differential are helical gears. They normally don't make noise unless they are worn irregularly. Low fluid levels are usually the cause of the irregular wear. This will cause the spacing between the gears or backlash to...

You will need to have the engine computer scanned again to get the codes and then properly diagnose any codes that are received. Fuel evaporative codes may cause the truck to run richer than normal but should not cause the...

Hi there. The axle play could be caused by the outer bearing on the transmission to be worn out. The bearing is inside the transmission, so to replace the bearing, the transmission will have to be removed from the vehicle...

Hello - usually power to the ignition switch, engine swap or not, comes through the fuse block. So, first thing to check is the appropriate fuse for the ignition from the Jeep Owners Manual. With the engine swap, unless you...

Hello! This can depend on a variety of factors, but specifically, your driving style can cause this. If you tend to drive harder than normal - meaning you tend to transfer a lot of power through the clutch by...

Hello, thank you for writing in. The power supply needs to run to that area of the dashboard before it is divided up between the different components. Considering that two components are both having a loss of power at the...

Hi there. An engine misfire is typically caused by an ignition timing problem. In modern cars, misfiring will invariably be accompanied by a Check Engine light. A code reader will tell you which cylinder is to blame, but it may...

Hello - either the relay is stuck in the "On" position from burned contacts or the heater switch is similarly stuck in the "on" position (internal contacts at least). I would recommend an electrical inspection by a mobile, professional mechanic,...

When the check engine light (CEL) illuminates, and stays on, you should have the engine problem diagnosed in a check engine light diagnostic. An illuminated CEL means that the computer controlling the engine has detected a fault or faults. If...

Hello. It sounds like the starter relay might be bad and is causing the starter to stay on, which is the clicking noise that you are hearing. There could also be a problem with the starter solenoid. The problem you...

A diagnostic would determine the root cause of the overheating. Common causes of overheating include a faulty thermostat (yours was replaced but that is no guarantee that it is presently functioning), a plugged radiator, collapsed hoses, and a faulty water...

Hello, a P0300 is a general misfire code without pointing to any one cylinder. There should be more codes present indicating which cylinder(s) have a misfire condition. You are correct in stating that a misfire is a combustion concern. To...

The brakes front and rear would need to be inspected for any excessive wear on the pads and rotors. The rear calipers may be sticking due to the caliper slides may make only one side of the rotor work. Have...

To answer your question about power on the ignition wire, if you check for voltage on that wire at key on and/or when the vehicle is running and you find battery voltage at that time, that would mean that the...
