Do you observe abnormal idle speed? It may be just an indicator fault; not a really engine firing problem.

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.

The injector is a good possibility, although you should check for spark in the wire first, as the electrical is the weakest link in the system. Put a spare plug in the end of the wire with the plug resting on metal, then have someone crank the van to see if you have spark that far, test and replace spark plug, (do not get shocked!) then look into a new injector or a good cleaning.

Misfired cylinder 6, replaced coil, plug Misfired cylinder 5, replaced coil, plug Misfired unsure which yet, all of these happening within a week. It will run fine for a day or so after rep


change all plugs with proper ones - they are picky for some reason - do not change number or brand from original - coils were probably ok, - get some injector cleaner and run through it but check for exhaust leak at e g r tube - is a common over looked cause of misfire - a thing to keep in mind is misfire isn't always spark issue. hope I was of some help

2003 town and country obd2 code p0300 fix


That is the multiple/random misfire code, as I'm sure you have researched by now. Do not rule out a fuel delivery problem such as defective fuel pump or plugged filter. Have your fuel pressure tested before you spend more money on parts. Low fuel pressure will cause lean mixture in some or all cylinders, thus multiple misfires. What symptoms are you experiencing, and when? Such as runs good cold but spits and sputters when warmed up etc.

Replaced 2 coil packs and still running rough 2003 trailblazer


try replacing or cleaning the injectors
when misfiring moves around it is seldom the coils , plugs and any thing else connected to spark but dirty fuel, low fuel pressure and dirty injectors or injector control
use a quality injector cleaner for a few tankfills

P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.
