My truck died a couple of times yesterday so checked the obd, and posted the codes 2106 and 2108 this morning in another thread. Everyone recommended that I clean my throttle body really good.

Did that, and started it about 20 times in the shop. Let it idle for a bit, drove it around the block a few times, all good. But after driving about 4 miles, shut it off, and it wouldn't start for about 45 minutes. Got it back home, shut it off, and wouldn't restart again.

Now its about 4 hours later, starts right up. So I'm thinking the throttle body must be failing once the engine bay gets hot???? Anyone heard of this? Wheres the best place to get a new one? I dont really want to go to the stealership...

 

Depending on year model and engine size, sounds like you may have an ignition coil that's getting hot and shutting down the spark.

 

Would it shut them all down? This doesn't sound consistent with what I've read up on this board.


In a couple of my other posts I mentioned the ETC light flashing, which usually points to the TB I thought..

Any other ideas?

 

This could be the problem if you have the 3.9, 5.2 or the 5.9 due to having a single ignition coil. If you have the 4.7 with multiple coils, this would not pertain to your engine. That's why I said "depending on year model and engine".

 

Sorry. It's 5.7 Hemi. Thats why I was confused. It has 8...

 

What year is your truck? Ive got 2 TB's sitting on the floor I was going to use for porting but wont be doing that. LMK what year you have and if you still need one.
