    Engine cuts out in wide turns

    Hey guys, I've been recently having a problem where my car will lose all throttle response only while taking exit/entrance ramps on the parkway. I'll hit the gas and nothing will happen but randomly it will start working again. I noticed my speedometer has been working on and off too and was wondering if this could be related? Anyone ever experience something similar? Motor is stock 325e m20b27

    Thank you

    Does it do it right after you get gas? Is it worse when the tank is nearly empty?

    Be sure to remind them that the M42 is one of the best engines ever made, but be sure to not mention where it actually falls on that list.

      Seems to happens randomly, no relation to a full tank or not. Did some more research, thinking maybe main relay?

        Oil pan ground if your cluster has issues at the same time - something to check!

          Where on the oil pan is there supposed to be a ground? I don't remember seeing one so that could be part of the problem.

            On passenger side of the car looking down in the engine bay you should be able to see it connected from your pan to the chassis.
            Your car won't start or run right without it.

              Just took a look and didn't see any grounds coming from the pan maybe not all cars have one?

                i had a similar issue and after replacing my fuel pumps, it was resolved. Its likely the low pressure in tank pump might be dead or weak. id start there first.
