Hi, thanks for the reply. Ground wire in the engine block looks fine and I uninstalled and cleaned it with contact cleaner, same as with the pedal harness and ETB harness, checked for loose and connection breakage too and all looks ok, but my problem remains that I get the R.E.D. Every morning only with po1516 code. As always problem is only when engine is cold. But if you rev the engine a couple of times after you start it in the morning R.E.D. Will not show up, and will be fine, but if you start it cold and not rev a bit it will throw out po1516 with R.E.D. Any idea what could cause this and why only when engine is cold?
