Question about 1989 Mercedes-Benz 300-Class
Hello, I drive a 1989 MErceds 300 E. When it is completely cold (just started) it accelerates like there is no tomorrow, when it warms up however there is a range (50-70 degrees C) where no matter how hard I push, the car simply will not go any faster. The economy needle goes all the way red and the car has actually stopped on hills wit hthe accelerator on the floor. The only way to get past the problem is either to wai until it warms completely, or to just drive on flat ground until it warms to 80. Once the temp gauge hits that 80 C mark though, its like the car is waking up and there are no problems. Any help on this would be greatly appreciated.
Jack the car up on the drivers side and block it for safety. Now look under the car at the transmission. If there is a block with an electric switch mounted to the trans(look right where the trans bolts to engine) then you have a shifter lock out that limits the rpm's until the catalytic converter warms up. Just disconnect it and you should be fine.
