Well in a way i am. hahaha. Anyway TS B16A has even worse FC compared to my 1.6 twin carbed 75 toyota with pushrod engine. I could not think of anyway to solve an EFI mileage problem from a second hand vehicle unless do an overhaul. A probable cause can also be part fried ECU, dirty sensors blah blah. That is why i suggest new car. But at the moment, TS will bleed through the wallet for fuel and second guessing where is going wrong by changing parts.Please dun be sarcastic, netmatrix.
