SOURCE: My car is misfiring around the 3rd cylinder, where

The third cylinder is the third spark plug wire from the passenger side of the car. An easy way to tell if this is the cylinder that is misfiring is to pull up the spark plug wire using insulated pliers with the car running. If there is no change in idle speed then that's the dead cylinder. If when you pull out the spark plug wire you see sparks shooting all over from it (a very common problem) then you need a tune-up.

Change your plug wires. If you want to, switch wires with another cylinder. If the misfire moves to the new cylinder, you found your bad wire.

Cylinder #1 continues to Misfire


What DTC code(s) are you getting?
You performed a compression test on cylinder #1; did you test cylinder #2?
Compare the readings, if there is a significant difference in compression readings between the two, you may have a bad head gasket, a bad valve, etc.
The bottom line, the problem is internal to the engine.

NEED HELP 2004 GMC ENVOY TROUBLE CODES PO301, PO128, PO301 PD RUNNING BAD- SLUGGISH AND VIBRATING. CONSUMING ALOT OF GAS


Hello cdhills06: My name is Roger and I will help you. The code P0301 is specific to number one cylinder. This means the cylinder is misfiring. The code P0128 relates to the coolant sensor. If you are losing coolant or have white smoke out of the exhaust? I would look real close at number one cylinder as having an intake leak or head gasket problem. Generally you do not have a cylinder misfire and coolant problem at the same time. Make sure you are not low on coolant in the radiator.Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

The error code p0301 ,This code is related to misfire.The cylinder is misfiring. p0301 this is the indication of cylinder number 1 ,that is misfiring.If the code comes up as p0300 this is the indication of random misfire from all the cylinders.But in your case its indicating p0301 this is indication of cylinder 1 misfire.Check cylinder 1 and replace the faulty cylinder 1 to clear the fault.The spark plugs and the wires connecting to spark plugs also needs to be checked.

Misfire #1 cylinder (autozone scanner) I changed all plugs, boots, and #1 cylinder coil. Went back to autozone and says misfire #1 cylinder. should I try replacing #1 injector now?


inspect the sparkplug plug first!! After engine is running for 20 sec (while misfiring), pull your #1 sparkplug and check for fuel. If there is no fuel replace the injector!!If there is fuel, post a comment for more help!!
