I would want to know if you have normal compression on all 6 cylinders, and if the other 5 are firing correctly.
Usually when you pull a wire and the engine smooths out, you have another cylinder miss going on at the same time.
How many trouble codes do you have in the computer ?

Still sounds like there is a fuel issue. I would check the obvious. Check the Air filter and fuel filter and water seperator. Debris could have gotten into the new injector, which also could have upset the other injector. Get the exact code from the dealer your truck experianced.

SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

SOURCE: rough running, erratic spark

Run a compression test on the cylinders.If reading is low on any drop a little engine oil into the pot. If compression rises you have compession ring problems. Remove all plugs before you try this and place leads away from engine.

Check engine light on engine acts as if missing new plugs wires and #5 spark pack missing again 6cyl 4x4 3.4 185000 miles


was it running this way before you changed the plugs? just a shot in the dark here possibly a defective spark plug, rare but not impossible. if it was running fine before changing them. Other wise I would take it to autozone and pull codes if it is P0350 #5 misfire we would use the process fuel, fire and compression. is there any engine coolant around any cylinders? Have you checked the coil packs? could be a bad coil pack. if no evidence of fluid around them proceeded to check for spark, fuel then compression. post back results or new post with more deductions. iis it no spark no fuel or bad compression.

I need help with my 1999 chevy silverado 1500 5.3 4x4 I have a rough idle like its only running on 7 cylinders here are some of the things I've done to try and resolve this issue, changed fuel filter


you need to isolate which cylinder it is first may help.
while running use insulated pliers to pull each plug wire off plug or cap separately, you will hear idle change/drop when a good cylinder is pulled. it will not change when not firing cylinder is pulled. now u got the cylinder and can double check plug, wire connections there. see if that wire sparks on a ground or plug to check spark and eliminate that issue. if you get a zap you need a better insulated pliers, but you know that wire is good. Remember the 3 things needed on all engines- Spark, Fuel, Air. oh yes and Compression. if you have spark, then have cylinder compression tested 120-150psi is still good. 80psi sucks and you have bad rings or valves., fuel cleaner may help in that situation, rare fix, but cheaper than a new engine.

What do I do next? My 2001 olds alero 3.4l v6 is misfiring constantly. Scanned obd2 error code p0301. Already changed spark plug, wire, and coil for cylinders 1 and 4. Still have same problem.


I recommend checking all injectors and O rings on the injectors if an O ring cracks air can raise Cain with misses so can injectors another thing is cam to look at will cause a constant miss but only on 1 cylinder at a time but doubt its the cam. check injectors and O rings also pull 1 plug wire at a time with wire pliers while engine is running and find the 1 cylinder that is giving you the problem when you pull the plug wire that is missing the engine will smooth out then that cylinder is your problem wear rubber gloves with the plug wire pliers so you dont get bit let me know if i can help please rate my solution as this is how i earn my achievements on fixYa thanks.

Car idles rough, sometimes dies in reverse, it's worse in cold.


A cylinder that doesn't fire could be 1 of 3 things: no spark, no gas, or no compression.
Sure, it could be a bad injector, or clogged, but you should do some tests before buying an expensive new injector. You should first check the injector circuit on #2 cylinder. It's a pretty simple circuit, really. Each injector has 2 wires, a power wire and a ground wire. The power wire is one wire, which is spliced to each injector, and has battery voltage on it anytime the ignition switch is on or in "run". Each injector's ground wire is a separate wire going into the computer. When the computer internally grounds for a split second that injector's circuit, the injector sprays fuel out a tiny opening, a nozzle. You can check the circuit for #2, both the power wire and the ground side of the circuit with a test light. Post back and ask, if you want me to explain.
You also might want to check the compression in #2, just to assure you there is no mechanical problem causing a loss of compression in that cylinder.

You could have 1 of these 3 problems.

1. The injector on cylinder #5 is clogged and not injecting.
2. The Ignition coil on Cylinder #5 is not firing.
3. One of the exhaust valves on #5 is sticking due to carbon build up.

Hope one of these gets you closer to the solution.

2004 GMC Envoy misfire


If you pull the #2 plug out and start the engine do you see a spark? You didn't mention if you checked the wires or not, but it could be a bad plug wire. If there is a spark, I'd try and see if the #2 injector is actually firing like you mentioned above.

1991 skylark ideling very rough


Misfire, a misfire is when you have a low cyclinder contribution this can be from a coil pack not firing to a open injector that is not atomizing the fuel in the combustion chamber to a large vacuum leak that is affecting that paticular cylinder.so you have a misfire. High HC (hydrocarbons) fuel not being burnt.2 misfire that concern does the vehicle rough idle smoothes out at higher RPM? If this does check the EGR it simple car running rough at idle feel the EGR is it hot to touch ? Then the EGR vavle got stuck open. another way is pulling out a spark plug wire and checking spark this will determine if the coil is working for that particular cylinder if you do this you need to make sure you dont break the plug wire you will have to wait for the engine to cool down and loosen the plug wire out of the sparkplugs and get it ready for a engine running test.

Code p305 help car runs good little rough on acceleration but runs smooth for the most part


P0305 Code - Cylinder #5 Misfire
A P0305 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #5.

Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present

Causes: A code P0305 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
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.


Test, check it and keep us updated.

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues
