SOURCE: check engine light comes on and car idle's and

I found this; if it helps.
The injectors need to be cleaned, if an engine is experiencing any of the classic symptoms of dirty injectors, such as lean misfire, rough idle, hesitation and stumbling on light acceleration, a loss of power, and higher hydrocarbon (HC) and carbon monoxide (CO) emissions.
Lean misfire may also trigger a misfire code and turn on the Check Engine light on 1996 and newer vehicles with OBD II systems. The code often will be a P0300 random misfire code, or you may find one or more misfire codes for individual cylinders, depending on which injectors are most affected.

Hope this helps

some weeks ago i had similar problems with my 2001 s60,i cleaned the etm and fitted a front o2 sensor ,its now idling at around 800 and driving fine.You could try changing the o2 sensor-but remember the earlier etms are troublesome and it may be a big part of your problem,the cleaning can work in only some cases

SOURCE: Bad idle, 98 Cavalier

**I have a 98 cavalier also. the air/oil separator was clogged with slug. there should be 2 tubes(1 to the oil, the other to the intake). my tube to the oil was clogged up badly so the one to the air intake wasn't functioning properly which caused a computer-like glitch which cause the car to stall randomly. no replacing nothing, just clean out the valve and the car should run normal again.

SOURCE: 2005 honda accord, rough idle and malfunction

I would take it to a local Auto Zone, or Advance Auto, they can run it through the diagnostic computer and see what codes are tripping, most likely it's going to be for a cylinder mis-fire, i would try making sure all the plugs are good, and check and see if all the plug wires are secured tightly.

I have car audi A3 2.0L FSI 2005 model when my start the engine is Misfire on idle in loss power what is problem my car can help me what is the problem in my car


Your 2.0T may suffer from excessive carbon build up on the intake valves. VERY common problem with direct injection engines since the fuel is NOT flushing the intake valves anymore. If you already experience misfires at idle, the build up is too much to be fixed with just a chemical cleaning; intake valves have to be cleaned mechanically.

What am I doing wrong? Cylinder 2 misfire will not go away. Tried everything. Even stumped a mechanic.


have a compression test done and look for a moving valve seat insert
it gives the knock, misfire
as it is no 2 cylinder it is mechanical because you have moved the injectors and coils , plugs and leads and it stays at no 2 cylinder
If you want clean engine oil then change the synthetic oil out and put in diesel oil 20w40
It will not harm the engine as it is the same as petrol oil but with more additives than petrol oil
it is cheaper and has heavy detergent properties that keeps the engine internals clean
from the gunk in the sump ,it is clear that changing engine oil on a regular basis is something you don't do but if you want a reliable long lasting engine , it is must do number 1

Misfiring


code p0303 refers to cyl 3 misfire detected ===causes engine mechanical fault--wiring--ignition/fuel system--injector--ECT/MAF sensor--ECM
code p0316 refers to misfire detected during start up --first 1000 revs===causes --engine mechanical fault--wiring--ignition/furl system--injector
the common fault cause is ignition/ fuel system and injectors so I would be checking fuel pressure and injector systems for clean and wiring connections are good especially on no 3 injector.

The Chevrolet Dealer Mechanic replaced the spark plug wires on my 1994 Impala SS. Three weeks later the engine started to misfire. I took the car back to the dealership and asked them to replace the spark...


What kind help you need?
You already know the problem is. So just replace the burn one.
and make sure secure it. Do not let it loop to touch the exahust
you should be good to go.

(Dealer machanic is same as the other one. They only have better equipment and new information available)

http://schematicsdiagram.blogspot.com/2011/12/how-to-increase-gas-mileage-on-2011.html---------

For car not changing gears it can be shifter assembly issue, or it can also be transmission issue. Get the shifter assembly inspected with ignition OFF.

For more troubleshooting, I suggest you to get the Following help link checked, its complete step by step procedure to inspect gear shift issues: -----

GEAR SHIFT ISSUES

http://alltypesofpartsreplacing.blogspot.com/2012/11/gear-shift-issues.html

==========




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.



From start to end troubleshooting these problems I suggest you to check the help link below and follow its procedure: -----


Mostly all types of car no start problems are discussed here with solutions.

ENGINE MISFIRE

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

My 2001 Chevy Silverado just got a newly rebuilt ******. The day i got the truck back the check engine light came on. I took back to mechanic and he ran the code. It said misfire and that truck was running...


did the code set for multiple/random misfire or did it set for a particular cylinder or cylinders?if it is random or multiple misfire you may want to check the fuel pressure and volume and for a vacuum leak. if it is a particular cylinder or cylinders then check your coils and also the compression to make sure the engine rebuild is good and something didn't go wrong.
