I accidentally used Deep Creep as an intake cleaner [SOLVED] Asked by STEVE MALENFANT M. In Alabama I just made the mistake using Deep Creep as an intake cleaner. Now the engine runs bad. What should I do?
No worries Steve. Deep Creep is not volatile like Sea Foam Spray (intake cleaner) so could cause spark plugs to foul. Any Deep Creep that you sprayed into your upper engine has worked out the exhaust valves so it’s long gone. All you need to do is remove your fouled spark plugs, clean the electrode ends… thread them back in and go.
