astra running problems

Hello,

I have a 2000W Astra 1.8CDX with 75k on the clock. I have noticed that when the engine is up to temperature the car does not seem to be running smoothly. It is only slightly noticeable and it is only when doing a constant speed or light acceleration. Heavy acceleration seems to be fine.

I have taken it to my local dealer, who for £30, told me there was nothing wrong with my car as none of the sensors were failing. He then suggested drilling a hole in the throttle body casing as this is what vauxhall has suggested.(The hole already existed, it was merely to make sure there was no blockage)

Another £60 lighter and the problem has not gone away.The car starts OK when hot or cold.I'm thinking it maybe a fuel problem, but that is only an educated guess!!!!

Thanks in advance

I guess that when you say doesn't run smoothly, the car kangaroos slightly, and seems to hesitate?

I'd guess a faulty EGR valve. This is one of the symptoms. They aren't always picked up as faulty by the engine managment. Cleaning the EGR valve may help.
