Nunions, just think for a moment that people will take about as much care to answer your question as you took to write it.

Plus consider that all anyone here has to go on is the one line of info you've written. It is impossible to troubleshoot what may be a complex problem from that. It could be many things. Firstly investigating all you can AND THEN asking with as much info as possible (like which version of 4AGZE, what car, when problem occurs, what fixes you've tried etc...) will make everyone's life easier and mean you stand a realistic chance of a helpful response.

Just re-reading, I don't mean to sound nasty. I'm just hoping to make it more likely that you get a useful response (and this also applies to many other forum members too)
