I take it you've done a fault code check.
I would be looking at, either lambda or CTS in the first instance. But as you know, sensor illimination can be expensive and trying.;) |

Lambda can be checked with a multi-meter and CTS is, Coolant Temp Sensor. It can fail open or closed, closed will give you difficult cold starts and open is like running full choke all the time.:thumb: |
Done this before.If you've still got standard ecu, plug it in, drive car off boost and see if it flings a cel up, then check code. Borrow an ecu if you've not got one....
