Throttle body

[#Jeff504lsv8]

About a week ago my throttle body went out so I bought a used one and I work fine for about a day now I have these 3 codes it'll crank up and run really good for about 3 seconds then it goes into etc failsafe mode... I just put new 8 ignition coils and spark plugs p2107
P0352
P2100

You may have bent/broken a pin in the harness when plugging things back in. It's easy to do.

Check the plug... and the socket.

Would that cause that p0352 code

If the vehicle has the original coils (or cheap coils) it would be best to buy new ones. The 3.9 is very finicky about coils as they age.

You could buy one and see if that helps, but that also means that the rest will need replacement at some point.

Most auto parts places have a scanner to see what codes are popping up. They should be able to make a diagnosis based on any codes.

It's all motorcraft ignition coils

The three codes I posted is off my scanner that's the only code that has

Well then... You may have a defective coil, depending on the milage. Or you may have a bad coil connector.

Try swapping coils and see if anything vhanges

It seems cylinder #2 is the issue. Passenger side 2nd coil back.

@#Jeff504lsv8 i had ETC Failsafe problems with my throttlebody. I took that silver electric motor cover off thats attached to it and found those magnets thats glued to the inside of the cover were coming unglued and were sliding down and hitting that electric motor causing my 06 LS problems until they finally binded that motor off and throwed it into ETC Failsafe mode.

Did your still rev up some when that happened? And Did you get the p0352 to ?

Its been so long ago i can not remember if there were any codes. But it seems like when it went into ETC failsafe mode that it wouldn't rev very high and it went into nuetral because i was almost home when it happened and i was able to coast to my driveway. I knew it had to be throttlebody related by the failsafe so i started taking my throttlebody apart to see if i could find what was wrong and sure enough those magnets were loose and hitting that electric motor.

@#Jeff504lsv8 Do you know for sure the throttlebody that went out on you was bad?

 

[#Jeff504lsv8]

It was making a bunch of noise like it was trying to cycle and I had no throttle at all so I just changed it

Ok with the codes you posted if you replaced the throttlebody with a good working unit and double checked all connections and coils are good then it sounds like you're pedal assembly maybe malfunctioning. Thats where i would go next.
