I have recently purchased 1993 190E 2.3 w/ 109k. It is in very good condition. This is the first Mercedes I have owned. The care seams to run fine compared with 4 cylinder cars I have owned. A little sluggish at low rpms (under 3000) but absolutely no power going up hill. You have to run at 4500 to 4500rpm just to pull it. I am just wondering is the 190E 2.3 (8 valves) shy on low end power are is there something wrong with my car? Any input would be greatly appreciated. Thanks
