ERROR CODE PO335 & PO300 - HELP!

[PTZIGGY]

Hi, I have a turbo 2005 with 53K, while driving a few days ago, the engine light started flashing and eventually stayed solid -car stumbled when I gave it gas - it has lots of hesitation. I was able to get home. It does idle fine. I retrieved codes PO300 & PO 335. I cleared the codes thinking it was a fluke. I was able to drive another 22 miles and the same thing happened again. I am expecting to have to go to the dealer, but I am not sure if the car will make it the 36 miles. Any ideas on what could be wrong? Any help would be appreciated. Thanks for your time.

Fault Code P0300 - Multiple Cylinder Misfire

A misfire code in a specific cylinder (P0301-Cylinder #1, P0302- Cylinder #2, etc.) usually indicates a possible problem with a plug or ignition wire. A P0300 code indicates the misfire is random and moving around from cylinder to cylinder. The cause here would likely be something that upsets the engine's air/fuel mixture, such as a major vacuum leak, leaky EGR valve or unusually low fuel pressure (weak pump or faulty regulator).

Thanks i am going to try & make it to the dealer tommorrow Am . I will let you guys know what happens .

The first thing they'll do is sell you and install a Crankshaft sensor and that might just fix both faults.

Thanks again for your comments. Is the crankshaft sensor expensive. It is something that I could buy in an auto parts store?

[CREWZIN]

We recommend that any of the sensors be bought at Chrysler. They may be a bit more expensive but there's been bad reports on sensors from aftermarket auto stores. Not exactly sure but the Crankshaft sensor should be around $50 and a little pain but can be replaced by almost anyone.

Well i just got back from the Chrysler/Jeep dealer and you guys are right on the money - they said it was the CRANKSHAFT POSITION SENSOR that was causing my trouble. They replaced that under warranty and also said my valve cover gasket was bad & that the plug wires were getting soaked with oil - so they replaced the gasket also - that was also covered under warranty - The engine runs much smoother now, I suspect I have had a bad sensor for a while & that it took along time for the fault to show. Before the fix the engine used to vibrate an awful lot while waiting for the light to change & the car was running rough and just didn't seem to have the pep it used to -Now the engine has smoothed out - it feels really good again. THANKS FOR ALL OF YOUR HELP - YOU GUYS ARE THE BEST! It was a real comfort going into the dealership & knowing in advance what they were going to say.

Glad it worked out. we see quite a few problems over and over again so it makes it easy to diagnose.
