2001 PT CRUISER MISFIRE CYLINDER 2

Check spark plug, plug ire and coil. Check connections.

check your spark plugs for marks and cracks ,check your wires for white marks on the inside , try spark plugs and wires if u still have a miss fire you may need coils #3 spark plugs that is you misfire

I changed my plugs and wires and my injectors. No change!! What else could I do?

I would start by having your codes cleared. If a fouled plug was the culprit, the pcm may not have reconized that it was fixed.

Try running a bottle of sea foam through it. You could have a sticking fuel injector.

As a last resort , have a compression test done. A crack in the clyinder head could also cause this issue.

I hope this gets you started :)

They are still looking for a cause because it isnt misfiring right now or because they cant find the cause of the stored misfire codes ?
If it is misfiring right now and they cant figure it out then perhaps you should find new mechanics !
I have seen a lot of bad coils on the PT.
Misfire is usually caused by spark plug wires first, spark plugs 2nd, and coil third.
If it isnt misfiring now, spray down the wires with water. If it misfires after that replace the spark plug wires and spark plugs and try again.
If it still misfires then the problem will likely be the coil.

start by doing a tune up. new spark plugs spark plug wires and distributor cap and rotor button if this does not solve your problem feel free to e-mail me at [email protected]

440 and 441 relate to the evaporative prurge flow system and 303 is a misfire detectec in cylinder 3.

Have your plugs and wires checked for replacement:)

That is the first thing i would suggest you do. Replace all the spark plugs and the plug wires. Those 2 things are the most commen thing that cause misfires.

The P0302 Code points to a misfire detected on the # 2 cylinder. If its stumbling, I would first suspect the plug or wire is bad. I believe the ignition coil on that vehicle is a single coil pack with four terminals, so if only the P0302 code is coming up I would start with the plug and wire. May be time to do a tune up and just replace all the splugs and spark plug wires.
