HI EVERYONE, NEWBIE HERE 🙂 I HAVE RECENTLY BOUGHT A 2001 2.2 ASTRA COUPE......AND THINGS HAVE STARTED GOING WRONG 🙁

*IDLES LUMPY ( PULSES AND VIBRATES WITH 2-3 SECOND INTERVALS)
*I HAVE FOUND A MYSTERY VACUUM PIPE THAT COMES FROM INLET MANIFOLD BUT I CANNOT SEE WHERE IT GOES INTO!!
*SPEEDO NEEDLE BOUNCES WHEN I GO OVER SPEED BUMPS ETC!!
*TRACTION AND ABS WARNING LIGHTS COME ON WHEN I GO OVER BUMPS ETC. AND STAY ON!

I KNOW THIS SITE IS FULL OF EXTREMELY HELPFUL MEMBERS SO ANY REPLY WILL HELP MY CAUSE!

KIND REGARDS

P.S.
*CLEANED EGR VALVE
*CLEANED THROTTLE BODY ETC.
*I HAVE DIAGNOSTICS CODES P0507 AND P0113

the traction and abs warning light is due to a faulty wheel hub sensor, my guess it's the nearside one as you are having speedo issues too.

have you any pics of the vacuum pipe as we can help.

BTW Welcome to the forum

if it is a hard plastic pipe then there is one on top of the manifold that goes to evap pump located on the side of the air box

the other hard plastic pipe is for the brake servo motor that routes around the back of the engine bay to the brake servo

on the side of the manifold is 2 connections, one is usually blocked off and the other is for the fuel tank vent
