general problems of the 2000 Nissan Quest

Nissan Quest 1. 0 I paid, and never reimbursed, for the cleaning of carbons deposit in part of the engine called throttle-body assembly in November 05, 2003. Mileage: 57,934. Ref. : superior court for the state of California for the county of los angeles - robert meyer vs Nissan north America, inc. Case no. Bc 263136. 2. 0 in 2006 my Nissan Quest started having problem to hold the idle speed at 750 rpm and the engine stop every time I am waiting at the traffic light. Mileage: 101,000. 3. 0 the Nissan dealer couldn't reset the idle speed and stated that to fix the problem they have to charge me over $2,000 without the guarantee that the problem will be fixed. 4. 0 I request that Nissan north America recognizes that this vehicle has a manufacturing problem and fix my vehicle without charge.

After engine is running for over 500 miles,(ie road trip)the van starts to buck and buck, engines hesitakes,no power is this a engine vapor lock problem. Dealer could find no problem with engine test machine.

Since April 7, 2003, I have taken my car in for a noise in the drive system. It was supposedly fixed at that time however, I have since been back 6 additional times to fix the same problem but they created new problems. I called Nissan consumer they order that the car get a new tune up although I had one in November at no charge to me. I have had my fuel injection work done 3 times since November. The car is starting to act up again with the noise in the drive system and again acting like it wants to shut off. I have had it. Please send guidance as to what I could do to get rid of this lemon.
