Hi,
Recently car has been very laggy while driving, especially in low revs. It is also very whiney. Originally I thought it was the Diff however I changed oils and had specialist check and all is ok. I can only put it down to the gear box??

Also, I have recently done a minor service, sparkies, fuel filter etc. After this, car is very ruff idoling. The revs drop so low sometimes, that it just drops out(especially when reversing and turning at the same time). Any suggestions on what it would be? Maybe freyd spark leads, injectors??

Any comments would be much appreciated.

Cheers
