the other day looked at my commander and the fuel pressure started going crazy. Just normal crusing down the road was around 11 -12 now its bouncing all over the place at idle, driving down the road cruising 55-70 mph and under heavy throttle all seems to be bout the same. Shut the truck off and bumped the key and listened to the lift pump it sounds good and strong. anyone have any ideas? is it just the cheapo sender for the fuel pressure?
Also have my smarty on sw 3 everything else on default except for timing and its on 4. there is quite a bit of timing rattle. anyone think this is too much timing? would there be a better combo for mileage? been getting 22 driving 70 down the intersate with that combo. thanks jared

 

Add a litre of 2 stroke(Tcw-3 ashless) per tank and the the rattle will fade to none (almost).

 

anyone else?
