My car ran great before the water pump & timing belt was installed. It still runs good, but when you first start it, it feels like it's running rough, and the car shakes a little sometimes, but you can't feel the miss when your driving on the freeway. Can someone please tell me what the problem might be? My son thinks it might be the vacuum line? Will I have to have the water pump and timing belt taken back off to find what the problem is? I'd appreciate any advise from someone who knows about the Infiniti QX4, thanks!

I had my brake pads and rotors resurfaced 6 months ago. Over the last month there was a horrible vibration noticable in the steering wheel when braking. Took the car back and they said the rotors needed to be turned again. Got the car back and it made a lot of wierd grinding/popping noises from front left wheel area. Took back they said when they assembled the wheel it was off by 1/16-1/4 of an inch. Since that time (one week ago), The car is not shifting into overdrive right (seems to be a delay and a lunge), there is a rattling noise which appears to be coming from the drive shaft (?) and the frequency of the car is off, most noticable after 40 mph. The car is a 2 wheel drive. Using the shifting lever, I can put it into automatic 4 wheel drive, permanent four wheel drive high, and permanent four wheel drive low. In the past, when I use four wheel drive (auto or permanent) it sounds lounder. It is currently sounding lounder since I got the car back after the repair of the incorrect wheel/brake re-install. Is it possible that when they fixed their mistake they put the left front wheel in overdrive and leaving the others out of four wheel drive? I don't know what the problem is, but I have had 4th gear (overdrive) transmission issues, drive train/shaft noises, and frequency noises since the brake/wheel was put back after turning the rotar. Does any of these problems have anything to do with the wheel/brake being re-installed incorrectly? Could the incorrect installation of the whee/brake after turning the rotor cause problems with the transmission? I also had the stabilizer bar links replaced but I don't think this has anything to do with the other problems.
