So loss power - codes come back misfire cylinder 1 cool long story short replaced all coils and plugs . Drives ok till u get on it up hills in the mountains to the point it shutters and backfires . Ford said it was a turbo , however my warranty company says it’s not ( which I agree with them. Boost is there but on load and u and in the hills is the issue

May as well check for the sludge in your intercooler. Drill the hole if you find any. It's in plenty of threads here if you feel like reading into it.

Awesome ! Will do - this ford store is a bunch of idiots - said it was turbos and wastgate staying open - but boost is all steady - really think it’s an injector cause of the back firing - the warranty company said to take it to another ford store - so we will see
