What is causing misfiring?


working scan tool free,
wow that be hard nut to crack ,no>?
wow no engine stated, which one?> 4.0L or ? 4.7L
not 2.5l diesel; sure.

The car has EFI

if you had that, we;d have facts
live data.
questions you can not answer
1: got DTCs.
2: WHAT IS LONG TERM FUEL TRIM BANK1 AND 2 IF BANK 2 EXISTS. near 0% or slammed in to +-30% rails.

3: DOES engine reach and hold 180F water temp, see ECT sensor it tells you that, scanned,
is the system holding closed loop status on both banks?

4: got pending dTC errors.
5: if you have p03xx errors P017x errors what are they and if true what is the freeze frame data.
and more.. but i stop here,

why not get car serviced at a nice ASE shop

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

==========




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.


CAR NO START: ENGINE NOT TURNING OVER:

----------




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.

For your trouble shooting I suggest you to refer the help oinks below. It has step by step details for many engine misfire issues.

96 Ford Explorer is studdering (misfiring) when going up hills


I have the same exact problem that just started immediately AFTER I got a tranny service where they changed the Trans Fluid, Trans Filter, Fuel Filter. Took it back and they say nothing is wrong with it. Took it to the dealer thinking I could get some REAL answers... they just told me to replace spark plugs, wiring & coil, for $900. Only studders when quickly accelerating above 40mph. I've check other forums, they say to clean the Mass Air Flow sensor. Haven't tried it yet. This seems the easiest before replacing spark plugs. Any other suggestions anyone?? Please.....
