Until a few months ago, this wasn't an issue for my W123. The vehicle is in excellent condition inside and out. Since it's not turbo, it's 'get up and go' has never been amazing. However, the vehicle has a difficult time reaching above 60 mph. <br> <br> Going through the gears has the same amount of torque and acceleration, but when 60 is reached, the petal is to the metal and that's all she has! The only other recent oddity are the OCCASIONAL times while being in Drive, the car sounds like I'm in Slow, maxing out at 40. Putting the gears in neutral and returning to Drive clears that up and it happens no more than once a month.<br> <br> I'd expect this performance to a degree while using the air conditioning, but this happens with or without the AC. Also, when the afternoon temps have been high, the problem would be non-existent and I could fly at my top 90.<br> <br> The tank's fuel filter has been changed...the other one was fine. I've added diesel fuel enhancement products on a regular basis. The air filter is new.<br> <br> The sensation of the vehicle in the mornings of late is like the engine isn't getting enough fuel or air - like it's being choked or constricted. I'm giving it gas and the car is hesitating VERY slightly. <br> <br> Does anyone have any ideas on what could be going on here?<br> <br> Rick Garner

I once had (in an Opel, but...) the hose from tank to fuel pipe bended a bit too much. It was bloking the fuel delivery, but only every now and then. There was also an upper limit for fuel consumption. How about checking the hoses and pipes from tank to pump?<br> <br> Next guess might be the linkage from pedal to engine.<br> <br> regards<br> <br> -r<br>

More on this and it might be looking ugly. I described my condition to another friend here in town who knows more about cars than I could hope - he fears that I may need a new transmission or pressure is low.<br> <br> The new info would be today - not only was I not able to get above 60, but when going up a hill and mashing the petal to the floor, the engine reved up, yet my speed slowly fell.<br> <br> I've always thought the transmission was fine as it shifted smooth and had great torque, yet it does feel weaker of lately. <br> <br> I'm goinng to give the engine a once over but do any of you have any thoughts on what I've said thus far and if it is the tranmission? If so, what are my options?
