Seafoam to the 1/4 tank and then run to near empty? Also, I checked with the tech from work, told him the same details, mentioned something about the throttle body and mass air sensor. I will try the seafoam first, shoudl i follow the directions on the bottle or how much should i put in the tank?
I will be fair, I realize your are diagnosing from a distance.
You can put the whole bottle in the tank. The throttle body shouldn't cause it to go through gas, the mass airflow sensor could but it is odd that it happened right after fuel injector cleaning. Let me know how it goes or if you run into any questions, thanks.
