92 400e w/ 160K mi. Starts up first thing in the AM after sitting overnight just fine. I pull out of the garage/Driveway and everything is still okay. However when I press more on the accelerator to get up to speed, it hesitates/stumbles a little. Only once and only first thing.
Could this be my fuel pump going south? When it happens its a pretty noticable hiccup

On this engine, it is usually the distributor cap and rotors. They are on the left and right side of the engines.

Check out he DIY section above for pictures.

I had this same problem on mine (same year and model) with 76K. I pulled the caps and rotors and they were in horrible shape. I figured they would get water in there, causing them to go bad at an early age. By the way, I live in a very humid climate. Anyways, I changed plugs, wires, caps, rotors, fuel filter and now the car runs FLAWLESS, seems alot quicker, especially when you stomp on the gas! The tune up is pricey, but hey, figure 1 tune up every 100K isn't that bad! Not many cars cand do this!!!!
