Ive been having a bad running problem, Car missfires under load. It will run fine for weeks then do this and once you clear the codes will run fine for weeks again, then fault again... Im thinking its the ecu going into limp mode cause it will run fine after clearing the codes. Read the codes today and im getting
00625 Vehicle speed signal, signal outside tolerances
00533 Idle air control regulation, lower stop valve
00530 Throttle Valve position sensor G88, Deviation from desired valve intermittent.
Car is a 8v ADY 95
Anybody shed any light?? Thanks
