Hi guys,
This is my first post here, I'm French and my English is not very good, but I'm reading the forum every day... :) I'm the owner of a beautiful 730i M60B30 manual, but I actually have some problems with it. Let me give you a quite exhaustive list om these :
- The start up is quite long, I think I have to keep the key on ignition about 3 seconds before the motor wakes up
- I've got a huge fuel consumption (about 30% more than normal)
- There are some explosions in the exhaust when I release the accelerator pedal
- When I'm driving at 2000/2500rpm, even with cruise control ON, the engine seems to shake a bit, or being quite unstable
- When I'm driving at 2000/2500rpm, and I put full throttle, there is a delay of 0,5s when the motor seems to strangle a bit, after that the acceleration is OK with some random little cutoffs
- The 2 last times I tried to start the car, after 4-5 days of inactivity, I had to insist 1 minute before the engine start up... After that there were some seconds where the engine was running rough, and finally it was running good. If I shut the engine off after that, and I try to start up again, everything's good !
Does anybody have an idea ? I'm really lost actually...
Thanks in advance !!
Romain
