Under steady speed / light throttle, motor jerks / bucks for no known reason.
I have a Omni power TPS sensor; calibrated via volt meter to spec.
Romeditor reads negative numbers, sometimes as low as -9 % when letting off the throttle, but settles at 1% when idling.
Could the TPS be the problem?
I have tried a new stock map sensor and already changed the map plug because of a bad connection.
Here is a datalog and the rom I am using. The car acts the same way with the stock ecu, so I think it would be due to a bad sensor, but no codes.
