Ford 3.0l 1st 1000 revs misfire causes - Cars & Trucks

now replace the coil packs

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 old give me money for nothing statement from a mechanic instead of knowing how to fix it.
code p0300 refers to random/ multiple cylinder/s misfire detected===causes--spark plug/s---HT lead/s---injector/s---ignition coil/s--low compression--wiring
code po303 refers to cylinder 3 misfire detected--- engine mechanical fault---wiring---ignition/ fuel system---injector --ECT/MAF sensor --- ECM
code p0306 refers to cylinder 6 misfire detected===causes --engine mechanical fault---wiring---ignition / fuel system---injector ---ECT/MAF sensor---ECM
code po316 refers to misfire detected during start up--first 1000 revs==causes--engine mechanical fault---wiring---ignition /fuel system---injector
code po2195 refers to heated oxygen sensor (HO2S) 1 bank 1 signal stuck lean===cayses ---HO2S---fuel pressure---injectors---intake leak
it also refers to O2S sensor 1 bank 1 same causes and also refers to HO2S 1 bank 1 implausible signal===causes --- short to positive---short to ground---Ho2S ---ECM
code po2196 refers to the same items as 2195 . some causes are also air intake restricted
Have a compression test done some where else and it will indicate the condition of the motor. The rest is sensors and wiring problems.

its normally behind the harmonic balancer under the front of the engine..

These codes are making me lean towards the ignition coil pack.My stepson's 2001 Sable 3.0 v6 had one cylinder misfiring(5-code P0305),which shares a coil with cylinder 1(code P0301).I diagnosed it by trading wire 1 and 5 at the coil,and the code changed to P0301.You have codes for the two cylinders on the same coil,so this is most likely it.(these codes would also trigger P0300(Multiple Misfires Detected) and P0316(Misfire Detected First 1000 Revs)).

PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...

A cylinder misfire

Forget the PO316 and 1st 1000 Rev,that is a Ford thing

No other PO Codes? PO 305 for cyl #5?

If you have individual coils (COP Ignition )
one is bad. Last number of a 300 code is the cyl
maybe. Unless it is really bad,then get back here
for more help

P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

Code P0316 means 'misfire detected first 1000 revs.'

Swap the coil pack with another cylender. If the error code follows the coil pack then replace the coilpack.
