You've got your own thread now

Right
When you say car ""slows down""

What exactly do you mean?

the engine is not performing consistantly,

Does the car shake / vibrate?
Does it sound rough?
Is the engine managment light on?

No lights on just as I drive it sot of holds back the power then picks up again as it's on a elastic band pulled back and then let go ,if that makes sence

When was the car Last serviced?
Has there any work been done recently?

I know what you mean when you say elastic band, my old mk2 was dying of slow death
on first startup, it used to pull badly, smoke like a bitch, and then suddenly like the elastic band had let go - it'd fly

The engine was toast, oil pump was suspect failure, as head was starved of oil, and cyl1 was scraping the bore wall = No compression

When was it last serviced was the question, mine was service regulary

Anything from a blocked air filter (dirty) to a block cat, to an inlet leak can cause result you are saying

What i said is what mine was - no guarentee's its what your fault is

i would be thinking worn plugs so putting a strain on system so the ht sparks find a quicker path to earth and then go back to the spark plugs
of course stage 2 in this scenario is a new ecu
