cheers ROB>

Sounds like its in limp home mode. Anyy ecu light?

[jamie gsi16v]

mine did this on the way back from pv show, the manifold had broke at the bottom making me loose loadsa power and when it was warm it limited at 4k, ecu fault id say

[Rob-16v]

Thought it mite be something lke that,i hope its not a big prob and it can be reset.

Cheers ROB>

yea stick a code reader on it to read fault and clear it.

Its prob air temp or sometimes a cam sensor- which actually is a phase problem due to the blet being slack

cam sensor this happend to 2 of my friends with 1.616v gsi's, the sensor kicks in at 4 and a half k revs!

only happned when they had the engine fitted tho!!

[Rob-16v]

Right then, got it sorted, i missed the single pin sensor off.........knock sensor :D anyway, pluged it in and it reves right round now, thanks for the advice guys,

Got a now problem now tho, it wuz ok for a day but now it idles at 3k once its got hot! wots that all about? any more help would be ace. cheers again guys.

[jamie gsi16v]

yeh you need this on and wired up correctly, i didnt n mine had a mind of its own, sumtimes it wouldnt idle then it wud rev its socks off.

[Rob-16v]

Does anyone know the bhp of an astra 1.6 16v x16xe?, is it less than the corsa and if so were is the power loss?..........inlet?

Cheers ROB>

The Corsa GSi with the C16 XE are 109BHP,
Corsa GSi with X16 XE are 104 BHP
Astra/Vectra X16 XEL are 100BHP

Main restrictions on all engines is inlet manifolds and can all reap great gains with changing to other systems.

Dont bother with powerbox's they are false economy and you will regret it.

[ben nova]

do you have an air flow sensor on your car if so take the plug off of it and see if it runs the same if it dose there's your problem ask me more if it is that :wink:

[Snowface]

AFAIK Corsa GSi/Sport was 106bhp.

Right is the c16xe inlet the plastic one and will it fit the x16xe head or are the ports the wrong shape? my engine dont ''bork'' and i think its because on the inlet. iv got a corsa gsi inlet off the x16xe, will this make a difference compared to the astra one?
