have you checked your plugs an ht leads?

Maybe your EGR valve, or have you got an induction kit?

I used to have this car and the same problem. It turned out it was the EGR valve when I had the ECU read.

wats a egr valuve and were is it located thanks

Exhaust Gas recirculation valve, located near the inlet manifold at the top, silver cylinder thing with a bolt either side. You can just blank them off.

wat u mean just blank them off

thanks

All they do is recirculate exhaust gas back into the engine, its emissions control. Its obviously not gonna do any good to the performance side of things so what people tend to do it make a blankin plate which is simply a piece of metal that goes between the manifold and the EGR valve.

what about all the pips going to it what do i do with them and what about the big black pipe to the box


thanks

Leave it all attached just stick the plate between it.

As far as i know, you wont fail emissions, personally i havent dont this mod myself, but u might get better throttle response.
