AbeltraminiR129

I just got another M119 swapped into my SL because of the old one haveing a terrible carbon built up. Whenever I step on it the throttle cuts out. It feels very similar to when the ASR/ESP comes on during a hard acceleration. But no light comes on and it doesn’t have anything to do with the traction. It’s happened on the freeway and other times. Usually when the revs are in the 4-6 range. It’s a 1997. My mechanic said it could be that the fuel injection is kinda clogged and. Just today I changed the Japanese’s spark plugs out for Bosch ones.
