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.

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.
