Just recently I have been having problems when starting my S1 Exige (with Emerald ECU). When I start it and press the throttle on idle the engine revs rapidly drop until I lift off. Doesn’t matter how slight the throttle press is. After idling like this for up to 5 minutes the problem goes away and it revs enough to be able to drive off under load.
The car is kept out and its been quite damp recently if you hadn’t noticed
So is it damp getting into it somewhere ? (I’m sure I’ve had the same symptoms even on the odd morning when it hasn’t rained overnight!)
Could it be a dodgy TPS ?
I presume I really need to hook up the ecu up to my laptop and see what the emerald software says though I haven’t done this yet. (Has anyone got the software they could send as I don’t have a floppy drive!)
Could it be anything else ?
