What will cause a Mitsubishi Montero Sport 3.5L to stutter and feel like it is skipping a beat when accelerating from a stop?
Case Details: Shifting to a lower gear reduces the problem. The Check Engine like comes on when the stuttering occurs. The problem is only when accelerating, not at idle or when cruising.
There are a few common causes for this to happen. The engine of this vehicle is equipped with three ignition coils, three spark plug wires and a power transistor. One of these is the probable cause. The first thing to do is the check the spark plugs and replace them if a problem is found. If the plugs are okay, there may be damage or a loose contact in the spark plug wires. If so, replace any that are damaged. If no problem is found with the wires, the power transistor that fires the ignition coils will need to be checked. Once the cause is found and fixed, the problem should disappear.
Should the plenum be removed to replace the spark plug wires on a 2001 Mitsubishi Montero LTD?
Since the intake has to be removed in order to replace the spark plug wires, then the plenum gasket may have to be replaced when reinstalling the intake manifold.
Is replacing spark plug wires part of the tune up for a 2007 Mitsubishi Galant with 70,000 miles?
The spark plug wires are not normally changed at this mileage unless there is damage or they are shorting.
What is the right way to check for a spark on a 2005 Mitsubishi Galant that will turn over but not start?
A spark plug tester or a screw driver is all that is needed. The tester will be available at most parts stores. Remove a spark plug wire from the plug and insert the spark tester. One person should try to start the vehicle while another watches for the spark. If there is a spark, starting fluid can be sprayed into the intake while the engine is cranking. If it starts a fuel supply issue is possible.
Will faulty spark plug wires contribute to catalytic converter problems on 2002 Mitsubishi Montero XLS with a 3.5L V6 engine?
An engine misfire can cause damage to the catalytic converter. Faulty spark plug wires are a common cause of misfires and other ignition related problems. The spark plug wires should be replaced before the converter is checked/replaced to ensure that the problem does not occur again.
What is the correct way to determine which cylinder of a Mitsubishi Galant is misfiring?
The simplest way to do this is by starting the engine and using insulated pliers to disconnect the spark plug wires one at a time. If the engine RPM drops when a wire is disconnected, the cylinder is firing. When the removal of a wire does not affect the RPM, that is the cylinder with the misfire.
Can a bad spark plug wire cause P0301 code on a Mitsubishi Eclipse?
The P0301 code is for a misfire in cylinder number 1. There are many reasons for this problem to occur and a faulty spark plug wire is one of them. Before replacing the wire, there are other possible causes that should be eliminated: a faulty spark plug or wire, a faulty coil pack, a faulty oxygen sensor, a faulty fuel injector, a burned exhaust valve, a faulty catalytic converter, running out of fuel/fuel pump malfunction low pressure, poor cylinder compression and a defective computer (ECM).
What could cause a 2002 Mitsubishi Lancer with 122,000 miles to continue to misfire under load even after a complete tune up?
A complete engine tune up involves many actions and a mistake in any of them or the use of non-standard or aftermarket parts can result in a misfire remaining after the job is supposed to be done. The vehicle should be taken back to the mechanic or shop that did the tune up for corrective action. One common cause of this kind of problem that is often overlooked during a tune up is the spark plug wires. Loose connections, corrosion or wire damage can all contribute to the misfire. If the wires have not been changed in the past, replacing them may correct the problem.
Why is the labor cost of replacing the spark plug wires and plugs on a Mitsubishi 3000GT more expensive than other vehicles?
Replacing the spark plug wires on this vehicle requires removing the upper intake manifold so that the rear plugs can be accessed. The book time for this job is 1.5 hours, labor costs vary across regions.
Spark plug wires are often overlooked as a cause of ignition problems.
