My Z16XEP Astra Twinport SXI is kangarooing like crazy at cruise speeds in all gears. Idle and acceleration is fine. Been to Vauxhall for Tech2 but no codes, spent £80 on a check up and bam - they say its the EGR. Unplug it and the car drives like a dream. Trouble is unplugged the car stalls on startup.
Now Ive purchased 2 used EGRs from feebay and a new gasket and the car still has the same issue. I really cant believe that 3 EGRs are faulty (including mine). I had a brand new ECU last year so dont want to think its that playing up . Also had a new coil pack, full service and new plugs. Could be a bad connection........I dont know, Vauxhall doesnt know.
So its time to blank - is this ok long term? Do I understand correctly that I could make a aluminium plate to put between the block and the EGR and leave it plugged up and this should be enough?
I see alot of people talking about blanking off the older MK4s or even reprogramming the ECU but mine is the late MK4 twinport so alittle different in design. I have a 4 bolt EGR that goes on the right side of the block, just below the ECU.
Thanks for any advice offered.
