Hey guys,


I have had an issue with hat I think is a grounding issue. When on freeway and change lanes and go over the little lane divider bumps or when on a very rough road my car will drop in RPM about 1k instantly almost like it dies for a second but then goes right back up to the original RPM I was driving at. The drop in RPM is very sudden and only does it when the car goes over a rough jerk or from a bump or like I said lane dividers for example. I think it’s a loose grounding wire? Have no idea what else it could be. Any ideas what this could be thanks for the help!

Could be a crank angle sensor wiring issue. Symptoms are stumbling and bouncing revs when then car warms up. Either replace the harness or run new shielded wires all the way from the ecu to the crank angle sensors. Or it could be a symple grounding issue. The wiring on these cars really sucks.
