So, Our VX berlina has become sluggish. When accelerating it starts to splutter. It happened prior to when we serviced it (Oil filter, spark plug - leads, fuel filter) Been fine for 5000k's. but now it's come back. I tried swapping Coil packs, nope. Tried swapping DFI, nope. Checked Vaccum lines, and any fuel leaks.. nope. Even tried error coding it, Don't understand it! Think the berlinas have a different thing. It's going 10 - 5 - 10 - 7 - 10 - 5 - 10 - 7 - 10 and repeats..... Someone please help us out?
I had a similar problem and every time I disconnected the leads and put them back on it was fine for a while but would end up missing again. The leads were relatively new NGK. I ended up buying genuine Holden leads and it's been fine for about six months now. VX have a four digit code but the numbers you provided don't make sense to me. The first two digits should be 00-- (10,10, I think)
Hmm, It started spluttering with genuine leads on there then we changed to NGK.... I've worked out the codes now.. so hard to find out about it, but sussed it out.. I reset the computer so I get a fresh reading of codes, now it's not spluttering anymore. It's odd. :\
I think 10 - 5 - 10 - 7 flashes might be code P0507, not sure though. If it is it means: Idle Speed Control System RPM Too High.
