Hi there. Check the spark plugs to see if they have burn spots on them. Switch them out with cylinders that are firing. If the other cylinders do not fire now, then the spark plugs need replaced. If the same...
Hi There, I think you are on the right track in thinking of things like the alternator or the water pump as those are two things that immediately will correspond to RPM change when accelerating. If it is the alternator,...
Hello. There are a lot of things that can cause this to happen. It really depends on if it is occurring only when the vehicle is moving or also if you just rev the engine in park. If the Check...
The catalyst should be replaced as soon as possible if it is bad. The backpressure on the engine will cause the engine to run with less power and may overheat the engine valves resulting in engine damage. the catalyst can...
There are two different places it may be leaking if not from a cracked housing at one of the pan bolt holes. The rear tail shaft housing or the shift linkage shaft seal could be leaking. Have the areas cleaned...
Hi there. What you're describing sounds like you may have a serpentine belt, pulley, or another belt driven component that has failed. The water pump is driven by the serpentine belt and cannot circulate the engine coolant if the belt...
This is likely a transmission problem dealing with the proper shift points. There is an ECU module in the transmission that regulates when the transmission shifts from one gear to the next based upon engine RPMs and activated by a...
Hi there. A rough idling engine can be caused by a number of issues, some of them are serious while others tend to be minor, but the symptoms remain pretty much the same. The car will feel rough and bouncy...
Hello. If the transmission is suddenly acting up like this and giving you this code then you may have gotten a defective transmission, or most of the time this is either related to the wiring or a control module problem....
If the engine is only stalling, or idling roughly, without putting the car in drive, then you probably have an engine management issue (fuel, ignition, air induction, etc.). On the other hand, if the stalling is only occurring once you...
Hello. It sounds like there is a problem with either the transmission control module and/or its wiring. There could also be a problem with the transmission valve body or clutches and if either of these are worn out this may...
If you want the mount that was engineered and manufactured specifically for your vehicle, you can order motor mounts from the dealer by VIN number. With regard to transmissions, the automatic versus manual transmission have different cases and thus necessarily...
Hi there. The front axle 4WD engagement switch is stuck. With the engine off and the transmission in neutral with the wheels chocked, remove the harness to the front axle engagement switch. Turn on the ignition to ON and start...
Hi there. The wrench light is a service indicator light that is designed to alert the driver that routine service or maintenance is required. In some cases, this light is illuminated when excessive carbon is detected in the fuel system....
It sounds like the latch that holds the door closed may be stuck in the closed position, preventing the door from shutting fully. This latch is located inside the door, but is visible while the door is open. It may...
If you can see the coolant line that is damaged, and can reach both ends of the hose, you should be able to replace the coolant line rather easily after removing the engine cover and air cleaner. However, on your...
This may potentially be related to a faulty transmission control module. As you may know, every time a gear change is required, the car's computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the...
The problem does need to be fixed. The steering wheel shaft may be binding in the steering column. You may also have another problem with the front end if the squeaking noise is not coming from the steering column. If...
The replacing of the serpentine belt is very straight forward. First make a drawing of the correct belt routing or look under the hood for a diagram with the belt routing. Release the tension off the belt by rotating the...
Hi, thanks for writing in. Your charging system and battery should be performance-tested to see if either one is not up to specifications. You may have a weak battery that takes a few minutes to get above the point the...
Hello. Although this may sound like a simple answer, it is very possible that you could have a loose ground connection near your battery. This is often times overlooked by even the best mechanics because it is such a simple...
The pop or clunk is the transmission shifting into first gear. If you look at this complaint on the Jeep Forums you will find many different opinions of what it may be and what fixed their vehicle. The first thing...
Keyless push-button starting systems are advanced electronic systems that utilize wireless and wired communications to communicate passive anti-theft information and engine starting permissions between several control modules (computers). The first item in these systems are the keys, which are not...
Your car has an electronically controlled transmission. The strange behavior may be due to a bad switch on the column, or there may be some reason why the program doesn't want it to shift into Drive or Reverse. Maybe it's...
Prior to performing diagnostics be sure you have a fully charged battery that passes a load test. Then, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. Basically, if a fully charged...
