Ronan S Posted February 21, 2016 Share Posted February 21, 2016 How's everyone?Been a while since I've been on the forum but having trouble and need some help!Not sure if this is in the right section so sorry if it isn't. Long story short,I fully forged a 5e,got a big turbo kit,cams and spec'd the head to suit and got it running. Starts fine and idles perfect when cold but once it heats up it sits down around 400rpm and cuts out if it feels like it.I've replaced the coolant temperature sensor,checked for vacuum leaks and no joy.Adjusting the screw on the throttle body makes no difference whether it's screwed all the way in or out.I took out the plugs today and they were black and soaked in petrol.It's running standard injectors,has an uprated fuel pump and is running 2.6 bar fuel pressure because that's the way it was set up by the lad who built it.I haven't been driving the car,it's done no miles but has been running periodically so it's only got a few hours on it.Any suggestions as to what might solve the problem?

StuDoc 72 Posted February 22, 2016 Share Posted February 22, 2016 (edited) How many rpm does it idle at when cold? Was it mapped? Edited February 22, 2016 by StuDoc 72 Quote Link to post Share on other sites
Ronan S Posted February 22, 2016 Author Share Posted February 22, 2016 Idles at like 1100 when cold and will drop to 400-500 when hot.Not mapped yet because I was told to run in the engine before mapping? Quote Link to post Share on other sites

starletezy Posted March 10, 2016 Share Posted March 10, 2016 Have you got a wide band to see if its running too rich or lean? if the engine isn't getting the right air to fuel mixture it might need a running in map Quote Link to post Share on other sites
5e colin Posted March 10, 2016 Share Posted March 10, 2016 (edited) its your cams ronan as u say and drop the pressure down to 2.3bar then reset your tb set rpm to 1000 this will give better tik over depends HOW BIG the cams are tho your rpm might need to be lot higher if there extreme Edited March 10, 2016 by 5e colin Quote Link to post Share on other sites
