ello peps i got a right pain in the arse car. a xr4i with a janspeed turbo conversion, the problem this time is when ever it starts it idles fine but as soon as the temp rises the engine stalls on idle but when it warms up more it idles fine. any ideas pls it would be well greatful.

Look at the warm-up regulator.... Mine's a bit clogged up at the min, an the probs your having are kinda similar.... If the regulator is faulty, the fuel pressure will be affected. I dunno if the turbos fuel pressure should be the same as a non-turbo, I cant imagine it is, but mine should be 3.2 bar, but it's running at 3.3 at the min, and when the engines warmed up, it can take a few turns to start it, yet when its cold, she starts, first spark!

Also, I'd check the distributer mechanical advance, I dunno the workings of dizzies, but I know mine has a fault there, the advance is fooked, so a refurbed dizzy is going on next week.
