engine miss firing

[william wason]

hi. just joined and looking for help .
i have a 1996 fiat ducato 590 royale 2lt. petrol engine and when i start it all ok , 1 minute later starts to splutter for 2 minutes until warm then all ok this sequence is the same everyday , l have changed
1. fuel filter , air filter , spark plugs , butterfly sensor , idle control sensor taken out and cleaned fuel injectors and opened them with battery to clean
2. thought it might be mass air flow sensor ( MAF ) need cleaning but engine dosent have 1
3. cleaned butterfly with carburetor cleaner in case of carbon build up
4. going to disconnect LAMBA sensor and try again to see if thats sending wrong info. to computer .
if anybody thinks of something i could try or change please let me know

Try HT leads..

hi. thanks for that but because of the timing of all ok for 1 min. the 2 min. of spluttering then all ok thinking of must be a sensor to give this same thing everyday , if HT leads where faulty dont think it they would give this timing affect but not 100% sure

The fluffle valve allows you to pour more compression into the plug holes. Only buy compression in tins.

odd kind of problem WW, some of 'us' try to help with 'humour' some takes some getting used to

welcome to the mad house we have only just resolved a similar problem with ours, but definitely not the same, TBH if it fixes itself by leaving on tick over for a few minutes I would accept that

Had a petrol car with a faulty Lamba sensor. started ok but struggled to accelerate.
Would go down the road with no power but after a few minutes the power kicked in and was ok for the rest of the trip.
Does this sound like your problem, got it replaced and ran ok after that.

hi. thanks for that . sounds just like my problem but did you start it and drive it straight away before letting it heat up , because if i did that it would struggle on road until heated then revs. would cick in and all ok

Yes started and ran it down the road, basically on idle, after a few minutes it started to run ok.
The car was a 1.8 zafira with only me in it so had a bit of power as it was empty, would run on idle.
I expect in a van you would require to put your foot down a bit and be off idle.
