as title, when i first start it, it runs very lumpy on idle and coughs a lot! after 5 minutes or so when warm it runs like a dream and drives perfect!

any ideas?

 

Dirty CPS? Dirty ISCV?

Failing that, burn it lol

 

Before burning it I'd try bumming it first!

 

always start with the basics mate

spark plug

leads

coil

then sensors , actuators etc etc

 

everything is brand spanking new apart from the coil!

 

has it only started happening since u fitted these new parts ?

 

parts were fitted years back, all genuine ford and brand new, car was laid up for a year in the garage (longest ive ever gone without starting it), so a year later when i went to start it the issue occurred! give it 5 minutes though and she runs perfect! car is bog standard engine wise.

 

Sounds like it could be the coolant temp sensor on the back of the inlet manifold.

 

that is brand spanking new a few years back from ford

 

Not burnt it yet? 😝

 

even newly fitted and unused things go bad when fitted and not being used, never rule out anything especially on a FRST
