Vectra Stalling

Hey all ive got a vectra b 1.8 ive been having major problems starting
the car and it drops immediatly under 500 revs and stalls this happens
even when i am driving? AAAAHHHHHHHHHHHH i have put a pipercross
induction kit in even a ecotek valve both are working fine but still
aint got a clue what the problem is....ANY TIPS

 

First, pull the codes, then clean the idle control valve.

 

Have you tried cleaning the idle control valve?

Or about 15 quid at your local garage.

idle control valve without a doubt,
very easy to do & you'll get the 'sporty' acceleration back.

while you are there, clean out the breather pipes to the engine that go to
the same place.

Works 'fine' ? You do realise it's a piece of useless shite
designed to rip off stupid people don't you..

 

so is the induction kit!
