Hi, I thought I would try picking your brains on an issue that is ruining my holiday, I have a supercharged car that is having serious issues when warm.
I am currently 500 miles from home touring europe and the car has started loosing all power when warm, it runs fine from cold but as soon as I get stuck in traffic or moving slower it coughs and splutters and I have to really feather the throttle to move anywhere. I am talking an inch of play on the throttle pedal anything more and it coughs and the power drops as if it is getting no fuel.
I run a 4 bar hondata map sensor which I have removed and stripped as well as the throttle body, thinking O2 sensor or IAT sensor?
Any suggestions would be greatly appreciated, as I don't want to waste anymore of my holiday than necessary working on the car!

 

Have a laptop and cable handy? Hook up to your aem and check the parameters at idle. Without a CEL, it's tough to diagnose so you'll need to see what the AEM is seeing.
