Hello took a look and couldn’t find a clear answer, one of my HT leads wasn’t working properly causing my lupo to misfire on idle. It’s a 2004 1L and the check engine light came on flashing before i messed about with the lead. I have ordered a replacement set of leads to hopefully fully fix the temperamental one but now my check engine light is solidly on and no longer flashing. Do i clear the check engine light or just wait until i change the lead and hope it disappears? Any help or advice would be greatly appreciated.
