I need to help my son who is broken down in Rawlins, WY pulling an RV.
He has a 2020 with the 6.2 liter, he was going up a hill and it started to misfire. He pulled over and it initially wouldn't restart on the third attempt it restarted but was running poorly. We pulled into a Walmart and upon looking under the hood he noticed a coil arching to the block, he replaced the coil but it was still running poorly and had fuel pouring out the exhaust. He scanned it and it come up with a code for the injector on cylinder 3. He has now replaced that injector and it seems to be running better, but there is still fuel pouring out the exhaust. I had him face time me so I could see and there is quite a bit of fuel coming out the exhaust.
He cleared the codes after replacing the injector and none have come back, any ideas on what it could be?

 

Fuel coming out of the exhaust?
You mean running out of the tailpipe?
Can't imagine liquid fuel would make it all the way from the engine, through the cats, and out the tailpipe.

 

Yes, out of the tail pipe, I didn't believe him either but I definitely saw it on the video. I thought it was coolant but he put his hand in it a smelt it he said it was definitely gasoline

 

More likely condensation or coolant, and smells like gas because it came down the exhaust.
Gas would have evaporated or got caught up in the cats and burned off, never would have made it as liquid clear out the end of the exhaust system.

 

Modern engines put out alot of water out exhaust. Really really uncommon for port combustion injectors to fail..

How many miles/hours?

Did he actually detect a misfire with scanner?

Can you describe the "running poorly" what was it doing?

 

Yeah the only way the liquid could be gasoline is if he had multiple cylinders literally pouring fuel through them, i.e. injectors stuck open, with zero combustion taking place inside the cylinders. Even then it would likely be only a small stream of fluid, it wouldn't be 'running' out the exhaust. Now running extremely rich due to pour combustion? Yeah, the water/condensation will smell like gasoline.

OP, sounds like the kid is up a creek, he needs to find a shop to take a look at this truck, or get it towed home if he has the tools at home. This is unlikely to be a 'quick fix' in a Walmart parking lot.

 

Thanks for the responses, the truck has 144,000 miles.
He is going to get it towed to the Ford dealer today

 

Hopefully its not a broken valve spring. And if it is, hopefully it didn't result in any further damage.
