SOURCE: engine misfire code multiple cylinders, starts

There are quite a few things that can cause this.
Check your fuel pressure to start. 55 psi key on is good.
Also make sure it dosen't fall back down should hold at that psi with out engine running.
Aslo the intake's like to leak air around the gaskits which will cause a miss fire.
Aslo the mass air flow.

Engine misfires. Battery dead/fixed. Po303 code: Changed plugs/wires, code cleared/reappeared. Misfiring again. Po420 code/then cleared. Po306 code. Replaced coil tower. Misfired again..


You either have a bad catalytic converter causing too much back pressure or you are running rich. I think cylinder 3 and 6 are on the same side of the engine (except opposite banks) right? Locate the fuel pressure regulator. Is it on the same side? I've seen those go bad and allow fuel to be sucked into the vacuum line causing a rich condition/ misfire on two or three cylinders on that side of the engine.

Cylinder 1 misfire detectedrich or lean air/fuel mixture fuel injecter fault and faulty crank shaft sensor


Wow... Thats a lot of diagnostic codes. First... The cyl #1 misfire will cause the Engine to run rich giving you a rich running engine. Therefore the rich lean code. This misfire on cyl #1 can also throw a crankshaft sensor code as it will slow down engine rpm. I would change the spark plug and ignition coil to cyl#1 and have the codes erased and see if that solves the problem. If not, you then need to persue any codes that may reappear.

Running rich


Hi Justin
you seems that you have a good idea about engines and injection systems, lets say that the computer see's rich exhaust and pulls back fuel mixture. creating misfire. why the engine is misfiring on one cylinder only??
my advice to you
1 search for a vacuum leak corresponding to the misfiring cylinder, like a manifold gasket or injector seal.
2, do a compression test for all cylinders, probably you have a burnet valve.
Good luck and let me know how it goes.

Hi Paul, Have you had a fault code relating to the knock sensor? That sensor controls ignition timing which can have a relationship to the fault codes you report? Regards John

There has to be codes. Well you melted another converter. Your injectors are leaking and the raw gas is overheating and melting your converter Your plugs are black that means way over rich and no codes? If you take the cat loose it puts a code in immediately

If its burning fuel and the plugs are black with soot, then its burning rich. the codes you said are P0300 generic misfire and P1153 heated O2 sensor B2 S1, I would first suspect that O2 sensor. Bank 2 is the passenger side (right side) of the engine and doesn`t explain why the left side plugs are black with soot, unless you say the left side by looking at the front of the engine. If this is the case then definitely replace the forward O2 sensor in front of the catalytic converter on the passenger side of the engine.

2005 chevy silverado v8, some hesitation, rough idling, ses light on and sometimes flashes. black smoke when reving the engine.


Black smoke could mean it is running rich, have a scan done, it is probably an engine misfire code and it will tell you which cylinder is misfiring. the last digit is the cylinder, unless it says random missfire, It may be time for a good tune up and don't forget the fuel injection system, Clean out the intake and do an induction cleaning on the injectors.
