Still having emission issues! C.o high above 2000rpm,drop below 2000 leval drops,thinking that map sensor is playing up.Car is a 1998 mpi with sensor in the ecu,going to recheck this week with p,scan to check the readings at differant r.p.m's.My question is if the map readings are out,has anybody bypassed the sensor in the e.c.u & added an external one,ie from a v.v.c?
