In a manual transmission, being stuck in reverse could be due to clutch and/transmission failures. You can try moving the vehicle slightly and/or manipulating the shift mechanism right on the transmission case. That may only provide a temporary solution, though,...

In my experience, I have never observed the differential to be the cause of vibration. The most likely culprits are the wheel or tire, driveshaft, or axle. You had the wheels balanced, so that will rule out balance or a...

A sinking pedal is often a sign that there is a leak somewhere in the brake's hydraulic system. Sometimes a problem of this nature may render a vehicle unsafe to drive, as braking systems relies on sealed pressure to operate....

This may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear, making turns (which makes use of the power steering pressure switch) turning on...

If you have a new rotor with new races already installed then there is no need to change them out.

If you used any sprays while working on the spark plugs the smoke may be from the product heating up and burning off of the exhaust manifolds. Exhaust manifold gaskets will also smoke for some time when newly installed on...

Hi there. The Idle Air Control valve (IAC) may have failed when you cleaned the valve with your cleaner solution. I recommend replacing the IAC with a new one. If you need further assistance with your engine idle surging (https://www.yourmechanic.com/services/idle-control-valve-replacement),...

Hi there - the rough running (https://www.yourmechanic.com/question/car-runs-rough) you describe could be anything from bad gas (water content), failing ignition components, or a fuel system problem (low fuel pressure, clogged or leaking injectors,etc.). The first task is to extract problem codes...

Hi there. Engine blow-by is the result of combustion gasses getting past the piston and/or piston compression rings, this builds crankcase pressure. The PCV (positive crankcase ventilation) valve system is designed to remove the pressure and recirculate the gasses back...

Hi there. Several situations could prevent adequate charging from an otherwise healthy electrical system. These include poor connections at the batter posts, power cables at the alternator, ineffective grounding between the battery, chassis, and engine (good connections and large enough...

There are a couple possibilities. The electric wiper motor has failed or blew a fuse, or the problem is in the wiper transmission linkage. When the plastic parts of the transmission are worn, the linkage can come apart. Grab a...

If the engine cranks slowly, you have a problem with the starting/charging system. If the engine cranks normally but doesn't start, you likely have a problem with fuel or spark delivery. In either case, it probably doesn't start after a...

The first thing to do is get out your lug wrench and be sure all of the wheel bolts are tight (https://www.yourmechanic.com/article/how-to-tighten-lug-nuts-by-john-hege) if you don't find anything that way, your problem could be in the brakes somewhere or even a...

Hi Hallie. More often than not, when you have this type of problem, it's mechanical in nature - meaning that a fuel or ignition system component has broken as opposed to a security system issue. If you are unable to...

If the exhaust smells like gasoline, the fuel mixture is either way too rich or you have a weak ignition system that is not burning the fuel efficiently. You can pull spark plugs out to check them and if they...

I am making the assumption that the skip you are referring to is a misfire that you are describing. There are several factors that can cause an engine misfire (https://www.yourmechanic.com/services/engine-is-misfiring-inspection). A defective distributor cap/rotor, bad spark plug, bad plug wire,...

You said that you changed the fuel filter and cleaned the tank, but did not say weather you had checked the fuel pressure. Checking the fuel pressure(s) is an important Diagnostic step on the old 240's with the K Jet...

Hi there. The modulator valve is located on the back of the transmission on the passenger side. The valve is vacuum controlled. So, before you replace the valve, be sure to check the vacuum line from the engine to the...

You could have a couple causes of the oil leak at back of intake manifold. (https://www.yourmechanic.com/services/oil-fluid-leak-inspection) This engine oil pressure sending unit is the most common leak in this area of the engine. Replace oil pressure sender if leaking. (https://www.yourmechanic.com/services/oil-pressure-sensor-replacement)...

This should not hurt the exhast to do this. I would recommend asking for a helper if necessary to help you keep the transmission level. If the transmission falls, this can damage the transmission rather than the exhaust. If the...
