How to Diagnose a Boost Leak (1998 Mitsubishi Eclipse GSX)


If you own a boosted vehicle, there's a chance you may have experienced having boost leaks. Boost leaks are caused when there is a small or large gap in the air system on the car. It could come from a hole in the intercooler, a loose intake coupler, or it could come from a faulty blow-off valve. Having a boost leak will result in having a loss in boost pressure and horsepower. 

When we were driving our new Mitsubishi Eclipse, we noticed that it felt a little sluggish and wasn't making as much power as it should. In today's episode of throtl, we walk you through the process of finding a boost leak as we diagnose the leak in our car. Check out the video below to see how we diagnosed the boost leak in our car and were able to restore some horsepower.
