First off a big thank you to everyone who has helped on here..without you guys I would've been in the poor house or the insane asylum last year....Now my 94 e320 has been the most reliable out of my 300cd, and even my 96 e320...but today I pulled out in front of someone expecting the same great giddy up an go jet engine speed I usually get and pUttt PUUTT puTTT pUTT.VROOOOMMM she takes off..hmmm.I think to myself..is she going to stall out at the light when I stop? Nope. Idles fine. Starts off fine. NExt light I decide to test her again..I accelerate hard starting out Vrooom! PuTT puTT puTTthen she kicks in and vroooom she's off again...anyone know what the hell is going on? The mass air flow was replaced new voltage regulator new air filtre she's been doing greaaat but today she started this freakin nonsense and I just got my 96 out of the shop after a new head gasket so I'm hoping this isn't some big $$$problem?
