so i hope i find hir a competent expert. my clio bj. 91 1.4L stutters when it is cold mainly between 2000 and 3000 tours but when it is driven 5 min (but does not have the full power) it also smells like too fat mixture whether hot or cold distributor is new just like the ignition plugs, air filter is free and the exhaust is also close in front of the lamda probe, plugs and underpressure hoses are on it and tight and now you 😉 best thanks in advance
