yet another issues arrrgh (rough on starting)

[rapidshed]

right yet again car is letting itself down,

starting up in the morning from cold, its rough and stuttery,

its not even that cold at present with it being summer, but when it fires into life, it splutters and runs rough then when its been going about 3 mins it seems to calm down!

whats causing this fault?

i have added 2 lots of redex to fuel to clean injectors etc.

Faulty mass Air Flow sensor? Mine was doing something similar even when warm.

[rapidshed]

ok if i change that, would i need to reset ecu yet again of will changing it judt be enough to do the business?

Maybe check and clean the EGR too - these will shows faults clearer at cold tickover than when the engine is warm if they have become stuck open.

Changing it would do the job but I'd be wanting to clear the fault codes in Planet.

My was running rough a couple of months ago. I replaced the MAF and noticed an improvement.

However, I also bought a can of that EGR cleaner and Miller's Ecomax and found the car to be running far smoother and more powerful than before:



and also check the air pipes.
