Hi, does anyone know please if the z18xe engine in my zafira '03 1.8 has got an egr valve or not.
I've been having throttle problems where basically i'll be driving along and my revs will just cut out. The engine wont stall but i do usually have to take my foot off the accelerator pedal then re apply to get my revs back.

I've cleaned the throttle body and sprayed carb cleaner into the intake but thats done nothing. The next step was going to be to clean the egr but i cant seem to find one.

The problem is very intermittent and patternless. I've also had it checked on the computer but no codes have come up.

Just thought i'd try a few cheap things before spending cash on guesses as to what the fault is

hi mate dont know if you found it yet but i have a w reg 1.8 elegance and my egr is on the right hand side of the engine above gear box, with a electrical connection on top with 2 x star torx holding it in place. i also have a similar prob at the mo but mine is only on tick over. if you have already replaced the egr did it fix the prob cheers

Thanks for the reply but i think your engine is the x18xe engine not the z18xe because it is the earlier 1.8 engine. I found out a while ago that my engine doesn't have an egr at all.

I have managed to fix the problem now but it was one of two things.
1- I cleaned the throttle body. If you look inside the throttle body there is one tiny breather hole which i completely missed the first time round cos it is that small. This was completely blocked with carbon crap so i fed some wire through it and sprayed carb cleaner until it was completely clear.

2-Whilst on AON LADMachining told me to try something else. If you press the brake pedal down with your hand and feel up towards the top of the pedal (you will need to remove the plastic cover around the pedals first) there is a little plunger which every once in a while needs resetting. Just pull it until you hear a couple of clicks then let the brake pedal go. This will reset it. I don't know exactly what this plunger is but it works alongside the fly by wire gas pedal and acts as another vauxhall safety point and cuts the power to the accelerator.

Silly of me but i did both these things at the same time so i dont know which one fixed my problem.

Hope this helps someone else
