1.8 16v cold running problem

[PhillT 0]

ok guys, I've spent over an hour searching and can't find much to help

 

:oops: (I'm sure someone else is going to post a link straight away knowing my luck! lol)

 

basically, now got a 1.8 16v rado, going to use it as my daily driver while I sort the IHI engine out and my Mk1

 

but it's got a running problem when cold, for the first 5 minutes or so, if I give it any throttle it's really lumpy, and chokes alot

 

anyone had this problem before? also know what the fuel pressure should be? (going to check the pressure tomorrow but I know it's not a pressure problem as I've had loads of pressure problems on the Mk1 before)

 

thanks in advance for any help you guys can give :thumbleft:

They run pretty bad when the warm up regulators are dead. FP should be 68-78 lbs.

 

You need to monitor it from stone cold and there is a special pressure gauge for doing K-jet incase you didn't know. Allows you to monitor control pressure as well as system pressure by opening and closing a valve.

The Haynes for a MK1 or MK2 has a small graph telling you what the pressures should be at various ambient temps.
