Occasional misfire clears with re-start

Post by starcar »

Hello
2004 1.6i Allure developed resent misfire, feels like a cylinder not running, engine light, antipollution fault sometimes catalyst fault. Cleared by switch off and re-start.
Tried coil pack, no codes stored, can't tell which cylinder and if it's always the same one.
Recent oil change and filter, decent oil. Plugs look ok. Injectors click ok on test, no petrol leaks
Any ideas?

If the engine light comes on then there will be a code. What are you using to check?

Hi

Yes there probably is at the time, but on restart the fault light goes off and no codes are stored or come up as pending. I have yet to be near enough to home when it happens to limp back and keep the fault active. I am using PP2000 on a laptop.
