Iv just put a new motoer into a vl calais i couldent get it to run to start with so i bridged the 2 pink wires under the dash now it runs but wont rev. It idles at about 3 to 4 hundred revs (to low) and when i put the foot down it will rev to 1000rpms and starts to die wont rev past 1000rpms. Iv tryed new CAS dissy cap & rottor button,fuel pumps,fuel filter, checked for air leaks changed o2 sensor changed ECUs it seems to have plenty of fuel and spark W.T.F could it be? Any help will be appreciated thanks.

Air flow meter?

Might sound dumb but is ya timing right?

Might be your ACC valve or AFM. When idling. Remove either the AFM plug or the ACC valve plug & see if there's any difference.

Iv tryed all of the above and still no luck any other surgestions.?

................cas? (standardised vl answer)

bump

Well, can it actually drive?? Is it like hitting a brick wall(loss of rev's) above 2000rpm??

what are these wires you bridged go to?

The wires i bridged were for the inobilizer they are on the ECU wiring loon. I can drive it but gets to 1000rpm and starts to die you can hear the air sucking through the air box its like its being starved of fuel or air im not sure.

besides the obvious ie plugs, leads, timing. as said air flow meter, i'd guess the wires/connection to the afm as most would know. or blocked catalytic converter

^^ as above esp the blocked cat why was the motor being replaced, any symptoms with the car prior to this work same engine as previous or upgrade?

engine was replaced due to the original motor had a blown head gasket and whatever else it wasnt in good shape. Ill try the cat and see if it is blocked thanks for that anyother surgestions???

Intank pump. Some original photos have not been recovered yet.

HTURBO,aus880 were spot on it was the cat converter it was blocked car is running good now thanks for all your help.

yes they were spot on lol. i'm glad you got it sorted.
