Does anyone have any accurate information on whether you can run a D4D with the intercooler removed? I want to de-crud the intake throat with some Threebond diesel conditioner and have received conflicting information from 2 separate Toyota workshops. One says not a problem, the other says not to because there's an airflow sensor that will shut the engine down if the engine is run with the intercooler removed. They also said you will get an error code that has to be reset at the dealer.
Which is correct? The Threebond product says you only need to run the engine for a couple of minutes while you spray it directly into the throat but I am unsure if it's OK to do so.
