SOURCE: intermitent rough idle & slight miss at low speeds

Trying to solve same problem on my 1994 ford Taurus. So as I see it just need to rethink what we did wrong to begin with and we could have put one of the wires on wrong (in wrong placement) or bad conection.

SOURCE: have code for cylinder #1 misfire on 96 chevy

these were bad for the spider injectors to fail. they are hard to diagnose with out the scan tool. the poppets in the end of the injectors get clogged and will need to be replaced. pull the plug and see if its oil fouled. they also have a problem with the #1 cyl getting out of round and oil fouling the plug. compare it to another plug in the engine. if its oil fouled the engine is no good.

Has p0300 code misfire cyl 2 and 3


If it was just cylinder 2 or 3, the code would be 0302 or 0303. Instead, you have random misfires (probably) such that you should be checking things that affect the whole engine. Vacuum leaks, bad plug wires, bad coil(s) or ignition module are most likely, but even clogged exhaust, O2 sensors and bad battery can cause these problems. Yes, a battery can be good enough to start your car but still be bad enough to affect performance. If I had to guess, I would start by testing the ignition module. Most parts stores can test this if you remove it and carry it to them.

I have a 98 chevy lumina with 61k miles.what can I do about these codes, P0300. P1381


P0300 is a random or multiple cylinder misfire, and P1381 is a misfire EBCM (Electronic Brake Control Module) or PCM (Powertrain Control Module) Since you mentioned replacing fuel components, it could be as simple as a fuel injector being clogged up causing a cylinder misfire. Have you checked your fuel injectors?

Multiple misfire


Hi Jason:
A Random/Multiple Cylinder Misfire Detected unfortunately doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

A code Random/Multiple Cylinder Misfire Detected may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer

Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

P0135 means 0xygen heater circuit malfunction, P0141 mean 02 heater circuit bank1 sensor 2 (this is catalytic monitor) P0147 means 02 heater sensor circuit bank 1 sensor 3, P0300 is random misfire. You will get all the 02 code because of the misfire correct the misfire and the 02 should correct.We will start with the plug wire and make sure the firing order is correct 1996 chevy blazer that will make it a 4.3 engine size check the firing order firing order is 165432 also check the coil (it has a tendency to short you will know if it is) cansmo_181.gifcansmo_182.gifmake sure the distributor rotation is check

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

My 96 chevy blazer has a code ''random 4 misfire'' only misses when in park or idleing at a light. is this and injector issue?


my 96 blazer would have random missfires.... sometimes more than one cylinder at a time... there are a few things to try.... 96 vortecs still used distributor caps... but they had such a high intensity spark that they were well noted for frying distributor caps and ignition coils... i would start there... also a few times i had to replace the crankshaft timing sensor.... it could be something as small as a spark plug wire... i would start with the ignition before spending money to check the fuel system

I have a 2000 Chevy Blazer. I can't get any current. No dash lights, no electric locks, etc and it obviously won't start. It does absolutely nothing when i turn the key. The gauges jump around randomly...


Check And Clean Your Battery Cables Really Good. Make Sure You Cut Some Of The Insulation Back From The Terminal To Make Sure The Cable Is Not Corodid Further Down.
