My MY 2000 has always had a small problem that seems to be getting worse.

When the engine is cold and if I put the engine under a bit of load then it starts to run really rough (no power , won't rev , idles at about 1,00 rpm really roughly).
If I turn off the engine and restart it always fixes itself immediately.

It has done this since new and the dealer has never been able to fix it.

I have had the MAF, CATS, and plugs replaced in the last 2 years and thes ehave not fixed the problem (they were rpelaced for different reasons though).

I assume the computer is getting it's knickers tied in a knot as I assume that by restarting the engine I am resetting the computer ?

Any other ideas ?

thanks

Doug
