So I have a 2003 GT convertible that was at a shop getting a new top installed. I get a call the other day stating that when they went to start the car it backfired and blew a baseball sized hole in the intake manifold (near the water pump). The only mods I have on the vehicle are an intake, Accufab TB/elbow, and it was tuned at another shop. The car ran fine prior to this. I tried perusing the web earlier to find answer, but to no avail. Trying to get an idea on how plausible this could be? Thanks.
