I wrecked my truck, no frame damage, collision shop replaced hood fenders, grill, radiator support and bumper. After the accident I started it and it was missing badly, picked it up from collision shop and it still misses. I thought, vacuum problem, cant find anything leaking, checked injector and pug connections also. At the time of the accident, I did notice the air intake was jarred loose, could it have hurt the MAFS?

Update.... will not give a code, I unplugged an injector to see if it would give a code and it did. Any clues?

 

Did you have it noted on your insurance report that it was missing? This should be covered by insurance for a proper diagnostic and repair.

 

I did, I was thinking it was something simple, I'm going to take it to the local ford dealership today

 

As much as I like DIY (and hated being without my truck) it's for the best to get it officially done. Repairs will probably happen faster, more accurately, not on your dime, and most importantly, you don't void out your repairs with the insurance company. Also you don't want to keep running it with a miss, you'll destroy your cat.

 

Update, took truck to Ford, after diagnosis....engine runs perfect, technician says something is broke on the outside of engine that is causing the vibration. I'm thinking possibly motor mount...any other thoughts?
