Fuel Issues

[t700]

My son had unloaded in Reno
Had the truck washed and a PM at Speedco yesterday.
Parked the truck at the TA and spent last night.

Took off this morning headed to California to book a load
got up to 1500 rpms engine started cutting out and threw codes 559 and 2346 which have to do with the exhaust gas temperature. These codes deal with amount of fuel going to the fuel rail.
I'am sure many of you can explain these codes better than me.

After realising that it had to do with fuel we went back to Speedco.
They checked the filter #s and said they were correct and bled any air out of system and stated what they had done was correct.

We still had the problem
After thinking on it we decided to have Speedco to replace the filters anyway
When they removed the 2nd filter the guy said that it was in fact the wrong filter.

Installed correct filter and all is well.
Reset all codes with Insite

Thankful we got it fixed
Hopefully this may help someone
