Re: [MBZ] 5.0 euro, replaced the fuel filter, warp drive back up sort of
I'd say at WOT your fuel air mixture is too rich, whereas when you back off the throttle the mixture improves (less fuel). Have you pulled the spark plugs, they sometimes tell the story. Are you able to adjust the mixture on your fuel distributor? The later KE ones have a plug to stop tampering (govt regs), whereas the K jet ones have a adjustment screw which takes a Allen key. Make sure that the Allen key is a good fit. Adjusting the mixture without a CO meter is an art form and not something that should be done without some knowledge of the procedure (read that as a disclaimer). To do this properly you should check your fuel pressures before turning the mixture screw. No good trying to compensate for a system running the wrong pressures. I STRONGLY ADVISE YOU TO LEARN MORE ABOUT K-JETRONIC SYSTEMS BEFORE ATTEMPTING TO ADJUST ANYTHING, YOU HAVE TO KNOW WHAT YOU ARE TRYING TO DO BEFORE YOU DO IT. Especially if you are doing this without the proper diagnostic equipment. Hendrik - Original Message - From: Kaleb C.

Re: [MBZ] 5.0 euro, replaced the fuel filter, warp drive back up sort of
guess I need to look into a fuel pressure guage. Maybe its not getting proper pressure? Maybe the used fuel pump I installed is not pumping enough fuel or something. Fuel pressure regulator maybe? I would think if something was still plugged up coming out of the tank it would be cutting out or something. David Brodbeck wrote: Kaleb C.

I does mention that performance gains can be made by altering the warm control pressure but like any HP gain you pay for it at the pump.
