Question about 1996 Ford Crown Victoria

2 Answers

Hi, I'm getting codes 136 02 sensor bank 1 sensor 2 along with 301 cylinder 1 misfire and 304 cylinder 4 misfire. Could the 136 be caused by the misfires ? I'd like to just swap out the plugs, but, they seem tricky to get to. Or could it be the coil pack ? 96 crown vic interceptor Thanks

I wouldn't worry about the 02 code it will clear when you replace the coils. to be positive that the coils are bad, swap them with another cylinder and see if that cylinder misfires. 90% of the time it's the coil. Let me know

Suzuki liana was running rough now won't start fault codes show p0134,p0340,p0400,p0301,p0304,p0300


no year car, no country no engines stated, what joy , PAR here.
lots of codes. a barrage of them.
first off i bet you didnt clear them (yes write them down thanks)
then see if they call come back.
this is SOP.
egr is 400
301 is misfire #1
304 is misfire #4
300 is random misfire, so all 4 do.
134 Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 1
340 is serious. means
Camshaft Position (CMP) Sensor Circuit
btw all but 400 is caused by 340

but since you posted with no facts, we cant help you can we.
each engine is different ,totally different.
you posted to a USA form that has no such car

The Suzuki Aerio (called the Liana - Life In A New Age - in )

and 7 engines.
all very different.

99 rx 300 I have trouble codes p0300, p0301, p0303, p0305, po172, and p0171.Stomped


codes p 0300 through refer to misfires on each cylinder with the end number ( 301 is no 1 cylinder , 302 is no 2 cylinder ans so on)=== causes --engine mechanical fault , ---wiring---ignition/ fuel ---injector/s---ECT/ MAF sensor/s ---ECM
most misfires are from injector faults like dirty/blocked tips, low fuel pressure , no pulse or problem pulse from ECM rather than plugs and wires and coils
codes p0171 refers to system to lean bank 1===causes ---intake exhaust leak---air system---maf/vaf sensors ---fuel pressure / pump---injectors ---heated oxygen sensor ( HO2S)
code p 0172 is system to rich-====causes ---intake blocked ---EVAP cannister purge valve ---fuel pressure --EGR system---injector/s ---HO2S
couple these two codes with the misfire codes , I suggest you look at the injectors, fuel pressure (too low) from EVAP problem not venting tank, fuel pressure regulator, EGR system

I have a mitsubishi delica space gear 2002 model that is misfiring we cant find the problem.


misfiring is more often from--- faulty injectors , wiring to the injectors and fuel pressure than plugs , coils and wires
the codes read fro p 0300 , 301-302-303-304-305-306 and each code indicates the piston that records the fault
misfiring can be from mechanical fault( loose valve inserts - burnt valves - to
wiring , plugs, HT leads, distributor cap faults ( in it doesn't have multiple coils ) , coil/s fuel pressure , injector/s injector wiring and ECM
You need to broaden the scope of investigation to get to the cause and one way to pinpoint the cylinder is to run the fault codes

What's your problem? my 2004 mercury monterey has eight codes ,po301,poo53,po106,po316,po300,po304,po305,and po306


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...

Po300,301,302,161,306 code numbers,what are they.upon acceleration it is like gas is having problem being sent to engine


P300 is random multiple misfire,301 is cylinder 1 misfire. 302 is cylinder 2 misfire & 306 is cylinder 6 misfire. P161 is a bad heater circuit in oxygen sensor bank 2 sensor 2. It is behind catalytic convertor. I would replace downstream oxygen sensor & clear codes. Run vehicle it may be all that is wrong.

P0171B


It means that your engine is running lean - not getting enough fuel for the amount of air that the engine is receiving. Because your maxima is equipped with a V-6 engine, whatever the problem, it is affecting only bank #1. Bank #1 is always the side of the engine where cylinder #1 is located, or in your case, the left side of the engine as it is viewed while facing the crankshaft end of the engine.
(on a 4 cylinder engine, there is only one bank and it is always referred to as Bank #1)
There are several things that can cause a lean condition including vacuum leaks, a malfunctioning Evaporative Emissions system, a misfiring cylinder (due to bad plugs, bad injectors, or an intake or head gasket leak.), a malfunctioning Mass Airflow sensor (MAF) or Manifold Absolute Pressure sensor (MAP) or even a bad Oxygen sensor (O2s) (Nissan sometimes calls an O2s an "Air-Fuel Ratio Sensor") It is even possible for a leaking vacuum brake booster to cause a lean code.
If there are any other malfunction codes present, it may help to pinpiont the cause of the lean code. (Like a P0301 "cylinder#1 misfire detected", in which case, you would address the misfire code first.)
Certain problems, like a leaking brake booster or a bad MAF will usually set lean codes for BOTH banks.
If the P0171 is the ONLY code present, the most likely cause is a bad O2s, but I recommend some diagnostic testing to prove it before spending the mega-bucks that Nissan gets for their O2 sensors.

2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced


  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?
