‘97 x300 4.0l. I checked codes and got P0300 and P1313. Car is running fine. It takes a little while to get to highway speed but otherwise good. Recently replaced fuel filter and all four O2 sensors. I was poking around just now and saw this fuel line that appears partially kinked. Could that be my issue?

 

The P0300 code was coming intermittently before I did the O2 sensors and fuel filter but I believe the P1313 is new.

 

G'day PBoudr,

A kinked fuel line could certainly be the problem.

I had a similar problem with my car and it turned out to be a kinked line from the fuel tank to the fuel filter. It looked like someone had attempted to remove the fuel tank without disconnecting the fuel lines from the tank and in doing so kinked the fuel supply line to almost closed which affected acceleration considerably, I only discovered the problem when I went to replace the fuel pumps as I thought that was the problem.

The OEM part was NLA so I re-hosed the line and it has been fine ever since.

If you replace your kinked hose your problem will more than likely go away.

Cheers,
Jeff.

 

Thanks Jeff, I'll definitely investigate that further. I appreciate the response.
