hey guys whats up ? I have been trying to get my GTP to pass emissions in MASS. but it keeps throwing a P0401 EGR insuf flow , which in most cases leads to the MAP or the EGR tubes, I have addressed both and still throw this code , so I used the hpt scanner and unchecked this code in the settings to make sure the light doesnt come on again which it has not come back on , but now the problem is I can not get my PCM to complete a drive cycle , could this be because I deleted /unchecked this code? the only test that complete are the o2 heater and o2 sensor, the EGR,EVAP and CAT wont complete . I just dont understand , any help would be great , Thanks!
