I was gettin a fault code for throttle sensor so I changed the throttle body and sensor and also the idle valve.

The rev dropping on pulling upto lights is still happening and it nearly stalls,.

Could anyone point me in a direction of wht else this could be

Cheers

 

Same problem on mine.

A freind said his did the same until he had it remaped.

Im waiting till ive fitted pink injectors before i map mine.

 

From my limit experience it could be a number of things, but since you have ironed out the obvious few things, I'd say if the car is mapped ask your mapper to look st it for you, if not mapped then maybe it needs mapping?

What's your car snd spec etc.

Possibly air inlet temp sensor or MAF sensor from my limited research. Do a search. Some have cured this with a spray cleaner, but depends what else might be wrong with the car/what's been modified etc. I'll be working on this on mine at the weekend so will post back my results.

 

will depends on what car? year also as some are prone to maf issues etc

Also what spec your running etc to help pin point the problem
