SOURCE: code 301, random or cylinder 1 misfire

Spake pluge could have gone bad, or the Spark Plug wire. Try changing all your plugs and wire and inspect the old one's. The wire could be bad do to time or may have been against the exhaust manifold and brunt. Good luck

SOURCE: Installed new distributor in 97 Chevy Vortec V6

Check the wire harness to the Ignition control module (ICM) or replace it. It cost around $40,00 from Auto Zone and it's common for the ICM to fail, or it may just be starting to fail and it's also know that the OEM distributor had a screen vent at the bottom of the distributor for ventilation to prevent condensation from forming in the distributor. Check to make sure your new distributor has a vent and that it's not plugged up with shipping plastic. Condensation may be forming causing the misfire in the distributor. Good luck and keep me posted.

SOURCE: My 1997 C1500 Chevy vent issue

Your blend door is probibly not moving all the way to vent position.If you put it on vent there is probibly air blowing on floor or defrost.It may also be opening just a fraction and causing back pressure on the blower motor causing the noise.Is there any difference in outside air or recirculate?

My 1997 chevy lumina 3100 v6 has ramdom misfires loss of power goin up hills and hesitation win i push gas any tips?


random misfires can be attributed to low fuel pressures and faulty injectors
with out any details as to fault codes found, check the fuel pressure at the manifold ( around 65 psi)

I have a 97 chevy tahoe 5.7 i just did a intake gasket due to the one given out truck ran fine befor i took it a part but now it runs and throws the p0300 code has a slight rough idle


P0300 random misfire, slight rough idle good , by the way your repair is good you dont want a identified misfire, Lets start by what it is not. Not a misposition sparkplug wire you would of gotten that cylinder code, as misfire, Oh try this got carburator cleaner? spray safely along the intake gasket, How about inspecting the vacuum hoses especailly at the map sensor. Here the thing you got. a vacuun leak. on a 5.7 a vacuum leak causes random misfire, by definition P0300 means 2 cylinders or more. By experience its a vacuum leak

I have a 1996 chevy c1500 that is throwing a p0300 code indicating random multipul engine misfire. this is the only code it shows I am familuar with older non computer engines but cant determine the cause...


Look at the plugs, if they looked hot and cooked then the misfire is unlikely to be electrical. If they look OK check out the Cam sensor connections on the edge of the flywheel housing. If the plugs are cooked it could be a duff EGR valve or, because you have no code, a clogged exhaust feed pipe to it. The absence of the introduction of a measured amount of exhaust gas to the mix would give rise to systemic overheating of the ignition temperatures and this in turn can lead to multiple fire events

Why is my Chevy C/K1500 misfiring? It is not the spark plugs or spark plug wires those have been replaced. It is the number 3 Cylinder, what could it be?


Compression, air/vaccume leak, pluged injector.
My guess would be a bad injector, GM has an update kit for all of the injectors, with all new injectors, a body, and fuel regulator!

Random Misfire on 2 & 3


I had a problem with a chevy with random misffires on all cylinders. It was the computer. Fords have very few problems with there computers. Does the check engine come on? Maybe have it scanned.
