Hi there, new poster so thanks for any help you can offer me! There are quite a few Qs, but any answers to any of them will be hugely appreciated.
Im mechanically aware but am not an expert at all, and dont really do work on cars myself.
My wife's Vauxhall Signum (which as far as I know is mechanically the same as the vectra as far as the engine bay is concerned) has the following problem(s);
HISTORY:
- The engine stutters and inconsistently loses significant power (to the point of having to pull over!). It has had this issue in various guises for a while.
- first off the garage replaced an injector, which improved things for a while.
- pretty sure the DPF was changed also.
NOW:
- The garage reports a fault P1125 which they are telling me is the throttle actuator, and around £245 Inc vat to fix.
- However whilst viewing this they have noticed the bar controlling the swirl valves on the manifold is disconnected/broken and want £700-800 to fix this.
- The vehicle is probably worth £600-900 but has just been fully serviced, taxed, and has a full tank! J so if its economical I would like to patch it up and get some more life out of it!
- Regarding the swirl valves, after some reading up, it sounds like I might be able to get an ECG blanking plate and fit this. Whilst not a fully reliable long term fix, this should sort it for some months I understand. However, when the ECG plate is fitted do the swift valves need to be locked open (?) or does it no longer matter as there will be no exhaust gas getting to them?
If they do need to be open, then whats the easiest way of achieving this? Ive heard they can be manipulated using a long screw driver, but I guess they might then move again, depending on how clogged up they are. I suspect they will be clogged up, which might at least mean I can move them and they are likely to stay put.
Assuming I can sort the Swirl valves cheaply... (as if I cant its the knackers yard!)
Im wondering if the swirl valve issue be causing / linked to the throttle actuator error. If so perhaps there is a way of cleaning and applying some lube and it might work again. If not I guess I will have to pay the £245, which might be worth it if Ive sorted the swirl valves very cheaply.
I feel like the swirl valves were probably the cause all along, and many of the other items have probably been replaced due to this, but who knows.
Thanks!
