How to fix a misfiring car?

Way to fix a misfiring car

Answer: Improve

There are a few things to do to when trying to diagnose a misfire. All vehicles are different, but there are a few places to start.
1)If possible use an OBDII scanner on newer vehicles. The misfire counter function can help you determine which cylinder is behaving badly. Clearly this is not an option for all people and vehicles though.

Note)Even without engine scanners you can identify which cylinder is causing a dead misfire. Carefully disconnect one spark plug at a time. If the cylinder you are disconnecting is operating properly you will hear a change in RPM. If the cylinder you disabled is the bad cylinder you will see no change in engine behavior.

2)Check your ignition system. There are several steps to this.

A)Remove spark plugs and check to see if the electrodes look worn down or contaminated. Check your spark plug gap with a plug gapper to see if the electrode has worn down.

B)Use a multimeter to check your spark plug wire resistance. They should read roughly between 2,000 – 12,000 Ohms. What you are really looking for is an open circuit in one of the wires. Bend the wires around and see if you lose continuity.

C)Check cap and Rotor. Look for carbon tracking or extremely worn down rotor.

D)On newer vehicles with distributeless ignition systems coils are prone to failure. If you know which cylinder is misfiring try swapping that cylinder’s ignition coil with another cylinder and see if the misfire moves with it.

3)If you know your ignition system is operating properly you may want to check compression. You may already have the spark plugs out from your ignition check so it only takes a minute to check engine compression.

4)Fuel injection Service – The motorvac service works miracles. It is available at most repair facillities. Adding a can of fuel injector cleaner to your fuel tank is not ecnough to clean out a severely plugged injector. The motorvac solvent is much more potent and should only be used with a fuel injection cleaning machine. It is a good place to check with a hard to find misfire.

5)Vacuum leaks – A vacuum leak will cause a misfire. If the leak is near a certain cylinder that cylinder will misfire. You can try to find a leak by spraying down the engine carefully with carb cleaner. If you spray the location of the leak the RPMs will rise. You can also inject the intake manifold with smoke from a smoke machine and look to see if it leaks out anywhere it is not supposed to.

Tips to know before choose an OBDII Scantool on-line

Tips to know before choose an OBDII Scantool on-line.

Will it Works with My Vehicle?

The most important aspect we tool buyers have to consider is that the tool we purchase must work with the troubling vehicles models. It’s true that OBDII is a standard, but in the market there are three different types of hardware communications used by OBDII vehicles. Some tools support all three and some are manufacturer specific. If you’re a diehard Chevy customer, you may be able to save a few dollars by choosing a manufacturer specific tool.

Supported parameters
Not all scantools are the same,actually, some ones aren’t even close. As part of the OBDII standard, the US Environmental Protection Agency mandated that on all OBDII vehicles it supports a basic set of  reading-related emissions. The SAE specification J1979 defines these legislated parameters. Many low-end tools only support these emissions related readings, giving you access to only a dozen or so truly useful parameters. While these give you some basic vehicle information, they are just a small set of the vehicle information available through the OBDII port. When shopping for a scantool, be sure to find out if it supports just the legislated parameters or if it also includes the enhanced (sometimes called proprietary) diagnostic.

It can be updated by CD or via Internet or not upgradeable?
Each year new vehicle models are released or existing models revised from vehicle manufacturers. In order to fully support the new vehicles, a scan tool must typically be upgraded. Professional quality scantools are upgradeable, although often at a price of $500 or more per upgrade. Most lower end handheld scantools are not upgradeable. Check what upgrades will cost before committing to a tool.

Scan Tools Built in Help about Factory Service Information
The Factory Service Manual have to be owned by anyone working on his or her own vehicle. But the scantool itself may be able to provide some of that necessary information. When a DTC is set, does the tool display the DTC number or give the full definition? A tool that displays the full definition will save a lot of time and frustration. Does the tool offer any information on typical readings to explain what the reading is? A simple sentence or two of explanation can save a lot of trips back and forth to the shop manual.

Data logging or storage
A 100% way to park your car in a ditch is to try and watch a scantool display while doing a roadtest. It’s very necessary that a tool stores data to allow safe viewing back at the garage.
