Holden Astra 1.8 TS 2005 missfiring when driving.
The car is missing and under powered. Replaced coil pack still the same.Took it to garage they put on their computer and told me the error codes said the cam angle sensor and the crank angle sensor needed replacing. Did that and they reset the errors messages, but they then still get the same error. they are now telling me i need to replace the cars computer unit itself - anyone else have any advice as it looks like these guys are just going to replace things systematically until the problem disappears but i cant afford it?
