Hi guys I've got a panda 2004 1.2 petrol. It's pretty lumpy on idle and can here a missfire ar tailpipe .. it does not idle smooth but as soon as you rev it it seems to even out. Drives normally except when you rev it or put engine underload it sounds like there's a metal tapping knocking coming from the engine...
So far I've checked timing all good
Fitted new plugs, coil packs leads
Injectors, if I remove Injector 1 or 2 it bogs down for a second then back to lumpy.. remove 3 of 4 Injector and it runs worse as in barely runs.
All 4 plugs were looking good( no heavy carbon or wetness) but changed them anyway.
Mes comes up with no other fault other than lambda after cat...
Could that be the cause?
Any ideas?
