Hey all im new to the forum but really love these old cars, i got my wagon when i was 16, and i am 17 now. it used to run great,but now when i gradually press in the accelerator the car will not accelerate and seems to bog down. By bog down i mean it slows down and doesn't pick up speed. Interestingly enough though, when i completely punch it all the way to the floor it takes off like a bat outta hell. I know i know, classic 17 year old testing methods, however i'm perplexed by this problem, ive put all new injectors in and a new fuel pump relay. could it be a timing issue, a transmission issue (it shifts sort of hard from first to second), a solenoid problem? i just don't know. it could even be electrical from what i hear but im curious to see what you guys come up with. I appreciate any of you that opt to help out a confused 17 year old. Long live Benz! Thanks!
