ML-430 acceleration problems & sputters
I have an 01' ML-430 it started having problems accelerating from a cold start about 1yr ago. It would have a very sluggish throttle response & sputtering then all of the sudden all the power would kick-in, after that it would drive fine. last week it got worse and I didnt drive it for 5 or 6 days. Now when I try to drive it will not go more than a few miles an hour and it is sputtering really bad, the more gas I give it the less response I get. If I floor it the car doesnt move but if I push the gas peddle 1/3 to 1/2 it will but very slowly and the power does not ever kick-in like before.
