my z20let dropped the following error codes:
P1243 - present
P1106 - not present
it was any malfunction, that mechanic kept the fuel pressure at 3bar after the insrallation of a larger injector (470ccm). i have right now phase 2 program, so when adjusted back to 2.5bar, the motor normalized. but P1243 left.
has anyone any ide what would be this? thanks
