Is it a 4 or 6 cylinder? 4 cylinders were bad about cracked heads and leaking fuel injectors. Check compression of that cylinder and adjacent. Should be withing 10-15 PSI of each other. Less than 125 PSI is not good either.

I have a 1996 GMC Jimmy that was iddling very rough and code said cylinder 2 misfire check engine light was on solid. Replaced all plugs, wires, cap and fuel filter 1st of March 2013. It ran better for a...


Lets start at the beginning. Did anyone check fuel pressure before and after replacing the pump ?
Has anyone checked the fuel pressure regulator and the injector spider ? The 4.3w engine uses a spider with one injector that supplies all 6 cylinders. And it runs at 65psi or more.

Diagnostic code p0301 idles rough after warming up, check engine lite is on, when accelerating check lite flashes and car bogs down letting up on gas helps engine catch up


P0301-

Trouble Code Conditions:
Engine runtime 3 seconds, engine speed change under 1200 rpm, and the PCM detected a misfire condition present in one cylinder during the 200 (Catalyst) or 1000 revolution (Emission) test range.Note: If the misfire is severe, the MIL will flash on/off on the 1st trip!

Possible Causes:

  • Fuel metering (fuel injector dirty) problem affecting Cylinder 1
  • Base engine (compression) problem affecting Cylinder 1
  • Ignition system (spark plug or plug wire) problem on Cylinder 1

2001 Mazda Milleniacheck engine light came on. .car is running rough and hesitates while moving. codes says misfire on cylinder 6. Had tune up. put in new distrutor cap. Still drives really bad. . ....


check all spark plug wires and replace. age and wear and tear will cause them to crack and therefore create the misfire in your cylinder causing the engine to run rough

Have misfire, code P0316, any ideals? 86,000 miles on


2004 Marauder and 2003-2004 Mustang vehicles built before 12/19/2004 equipped with 4.6L 4V/5.4 4V engine may exhibit a runs rough, lacks power, and engine misfire, prompted by a MIL light and DTC codes P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, and P0316.
ACTION
Diagnose engine for engine misfire concern. If diagnostics determine an engine misfire which is characterized by leakage through exhaust valve(s), only replace the affected cylinder head(s).
SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8.

I have a 2000 buick lasabre that has been running very rough, my son put computer on and it said bad o2 sensor, he replaced sensor, and it is still running rough, but the computer now says cylinder 6...


plugs and or wires.
for some reason the spark is jumping out of the wire or plug.
the plug insulater may have a crack in it.
also use a carb spray to clean out the throttle body at the throttle plate.
all the black carbon will build up around the throttle plate and restrick airflow at an idle position.

hope this helps
thank you

P0301 trouble code....have changed coil pack, plug wires, plugs. seems to run rough on cold start and then comes out of it


The misfire is detected by the misfire monitor as a slight change in engine speed which the PCM calculates back to a particular cylinder. The monitor is active continuously, but associates problems into 3 types. Two of the types are monitored on successive trips. The first trip the monitor detects a misfire it sets a pending code but not the MIL light. If on the second trip the same problem occurs the DTC code is set as current problem and sets the MIL light on. The MIL will stay on untill the DTC is deleted. The remaining type is a most sever case and signals the possibility of cat damage. In this case the misfire monitor identifies the problem and the PCM determines it to be severe and immediately sets the DTC as current and the MIL light to flash at a rate of 1 per second until the condition is no longer present, at which time the MIL stays on steady.

So once the P0301 is set it never turns off, except by code deletion procedure.

I think a lean burn condition could cause a misfire, but probably not from a PCV problem which should affect all cylinders equally. There would likely need to be another problem with that cylinder or intake or ...... .

Cylinder 4 misfire on a 2000 crown victoria interceptor


first cylinder 4 is the last on the passenger side . first pull the coil out and check if there is water where the plug is. if there is take the water out and dry up the coil. if you find water you got a crack manifold or a bad intake manifold gasket. if there is no water replace the coil. good luck

Random multiple misfirings


Here is a list of possible causes. You should not drive the vehicle if the check engine light is flashing all the time, you can cause even more damage. It could pay to have a professional find the real cause.

Spark plugs that are incorrect for the application, cracked, improperly gaped or worn can cause the engine to misfire or run rough at all times.
An IC module that failed to correctly control the ignition coil(s) will cause the engine to misfire or run rough at all times.
Poor connections, broken wiring or wiring that has shorts to ground can cause the engine to misfire or run rough at all times. NOTE: Check connectors that might be pulled apart as the engine flexes or wires that short to ground as they pass near brackets or shorts to ground on the exhaust manifold.
Fuel injector(s) that are shorted, plugged or partially restricted can cause the engine to misfire or run rough at all times.
An ignition coil(s) that has low output, corrosion on the coil tower(s), is carbon tracked or arcs to ground will cause the engine to misfire or run rough at all times.
A PCM that failed to properly control the injector or ignition timing will cause the engine to misfire or run rough at all times.
