thanks for your quick reply peter.

The fuel filter and pump are about the only 2 thing i've not changed...lol

In the last week she has had new plugs, coilpack, throttle body taken off and given a good clean and the egr valve blanked off. I bought the opcoms diagnostics tool and cleared a load of old codes, took the car round the block and had 166 misfires and the code 0300, if that helps.

I will get a new filter tomorrow and see if that helps, if not then its a new pump and that will be another 2 things struck of the list. Thx

hi unthrottled, I took egr off and tested it and it was stuck open thats the reason m8.

I just unplugged all sensors and plugged them all back making sure they were all secure, took the car out for a 15 minute drive and it ran not bad but not 100% but alot better than it was, It still felt a bit rough when idling.

There was a sort of screaching noise not that loud but loud enough to just hear above engine coming from the throttle body, could this be anything?

Thx for your input m8 all helpis most appreciated

hi ive got the code P0300 up on autodata now and it says

random multiple cylinder(s) misfire detected

cause spark plug(s), ht lead(s), injector(s), igition coil(s), low compression, wiring

i hope this helps

kind regards Neil

just had car out again and done the same again, if i clutch and free wheel then start engine again it runs fine for a couple of minutes then goes back to running rough.
