Misfiring Landrover Serengeti 2.0L TD

My car is misfiring and sometimes not starting due to this problem. It misfires on Idle too. The Air filter has been changed and its had an electronic diagnostic check that just showed reduced pressure. The Engine keeps coming on and going off. Sometimes the misfire is worse than others. Any Ideas ?

And for .......

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

SOURCE: I have a 2003 landrover discovery and it has about

Hello trish...you must have a really fancy code scanner because i have never had one tell me that...lol
When you say "mass air flow filter" i assume you mean mass air flow sensor (MAF)? If your check engine light is "flashing" it's telling you there is a more serious problem to be dealt with and you should have it repaired now to prevent additional faults..and possibly costly repairs in the near future.
On your landrover the scanner should read "Manufactured Control Fuel and Air Metering" fault if it's a MAF sensor fault. This fault does NOT always mean the sensor is bad, in most cases the sensor is fine and is doing it's job by reporting to the computer a problem it has detected...
The MAF tells the computer how much air and the temp of the air that the engine is getting.
Then using those readings and the readings from your oxygen sensors and the gear your in, engine speed, engine temp, and the list goes on and on the computer gives the engine the correct amount of fuel for the load it's under.
There are ALOT of variables and if one or more is out of sync it screws everything up...it's like a domino effect..are you with me still?
...After you replaced the sensor...did you rescan the landrover and clear the codes...because if you didn't...the computer still has it stored and nothing has changed? let me know what you find on the next diagnostic scan...that blinking light is not good.
Good luck..i hope this helps ya...please take time to rate me a fixya...
PS: make sure the gas cap is secured properly.

SOURCE: Engine misfire...

First off what you want to do is see if the coil is keeping fire to the cylinders. If so is the fire blue or redish/orange. If it is blue then its not a firing issue. If it is red then you probally need a new coil. Now if you chose option A then check the spark plugs and make sure they aren't fouled out. The way to determin this is that they will be black and smell like gas really bad.If not then check the spark plug wires and make sure they are not ripped, broken, cracked, or show any signs of failure, If not then make sure it is getting plenty of gas. If not then it is either the fuel pump or the fuel filter. If it is a fuel injected engine then make sure the injectors are all working properly. To do this you will probally have to bring it into a shop and have them check. If it is a carberated engine then manually chock the carberatur by holding the top flutter valve closed for a second or two. If the flutter valve gets covered in gas real quickly (in less than 2 seconds) then it should not be a problem with the carburator. If you are still haveing problems with it after checking all of this then give me a shout back and i will see what i can do.

How do I fix, bad idle in suzuki swift , check light on, no codes.


the title is contradiction
" check light on, no codes."<< totally wrong
scan it one more time with a REAL scan tool this time. (there are DTC errors , or codes as you said)

what does bad idle mean? misfiring, or idle speed too low
or too high? RPM, or
surging?

say what that means please.
and more important is engine hot or cold ? failing.???? or both????
there are over 50 causes.
but can be broken down to simple physics and gauges.
1: engine bad, lost compression.
2: engine cant breath, dirty air cleaner
3: ISC stuck closed or open or just stuck. (bad idle air supply)
4: bad spark, 1 or all 4 (never had a tune in this decade.
5: cam drive, slipped (belt) causing #1 failure.
6: air fuel mix too lean, and causes rpm drop and ISC fails.
7: air fuel mix too rich and misfires.
8: egr stuck open, it misfires and ISC gives up.
9: cat clogged, engine cant breath #2 like.
10: and the vast other reasons for misfire.

we cant drive it, see it or hear it misfire, so.....????

there is a test for all 10, ask. or get car serviced.

Misfiring on bank 1 3 and 5


misfiring is also from injectors and low fuel pressure. To be all on the same side I suspect injector wiring ( possible loose connection on the ECM). Have a compression test done to delete mechanical problems (valves)

2006 cobalt 2.2 engine, when engine is warm it has rough idle and dies when stopping. it runs fine if not trying to stop. car has 136,000 miles, plugs were changed at 112,000.


You replaced the spar4kplugs but how about the plug boots, these boots are like sparkplug wires and they short out sometimes , with over 100,000 miles i would replace them, also you may have a bad coil . the coil is a complete unit its 4coils in one and may be misfiring, the other problem maybe a dirty throtlebody or bad idle air control valve, you said it runs rough at idle, i would first take it to have the computer scanned to see if there are any stored codes, the computer is always yesting all systems and when it sees a problem it stores a code, this code will tell you what is failing, many autopart stores will scan it at no charge, also if it sees the problem a certain about of times it will turn on the engine light, if you get it scanned and give me the codes i will be able to help you further. for example they may scan it and get a code that reads po302- cyl 2 misfire. this means cylinder 2 is misfiring and then you need to see why its misfiring, it may be due to a plugboot or coil or injector. i would scan it first. hope this helps. good luck.

I am having ongoing problems with the truck miss firing and rough running. Timing is ok, replaced cap and rotor,coil. It still starts rough,idles rough and misses when at cruising speed,although it seems...


Misfire is a common driveability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle. The engine also may be hard to start and may even stall at idle, depending on the accessory load (air conditioning, headlights and electric rear defroster, for example).

When misfire occurs, performance suffers along with fuel economy, emissions and idle quality. And, when a misfiring vehicle is subjected to an emissions test, it will usually fail because of the unusually high levels of hydrocarbons (HC) in the exhaust.

What causes a cylinder to misfire? Basically, it's one of three things: loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression. Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad spark plug wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.

"Lean misfire" can occur when the air/fuel mixture is too lean (not enough gasoline in the mixture) to burn. This can be caused by a dirty, clogged or inoperative fuel injector; air leaks; or low fuel pressure because of a weak pump, restricted filter or leaky pressure regulator. Low fuel pressure would affect all cylinders rather than an individual cylinder, as would most air leaks. A leaky EGR valve can also have the same effect as an air leak.

Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited. The most likely causes here are a leaky (burned) exhaust valve or a blown head gasket. If two adjacent cylinders are misfiring, it's likely the head gasket between them has failed. Also, if an engine is overheating or losing coolant, it's likely the head gasket is the culprit.

Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load or operating conditions. They seem to occur for no apparent reason. The engine may only misfire and run rough when cold but then smooth out as it warms up. Or, it may start and idle fine but then misfire or hesitate when it comes under load. Also, it may run fine most of the time but suddenly misfire or cut out for no apparent reason. Intermittent misfires can be a real challenge to diagnose, so let's start with a steady misfire in one cylinder before moving on to intermittent misfires.

Hope this help.

Misfiring


A typical tune up includes spark plugs, air filter, fuel filter, spark plug wires, distributor cap and ignition rotor. You must determine which parts are needed before you start.
I would suggest to first check spark plugs and spark plug wires.
