Manifold/header/muffler/tail Pipe problems of the 2000 Mitsubishi Eclipse

When putting car under full throttle, intake manifold splits at the part where it connects to the throttle body. This causes engine to shut down while driving, including loss of power steering, etc. Can be very dangerous. Replacement of manifold is $300+ for labor and $600+ for parts. Many others with same engine type (4g64) have had exact same problem.

I purchased my car new from modesto Mitsubishi. At the time it was noted that the sunfroof molding was not installed correctly and was to be replaced. I started having problems with overheating, electrical malfuntions, mirrors, clock, casette door defect, also sunroof opened only while getting on highway. I took vehicle to dealer, and ended up having to rent a car for about 3 1/2 weeks while they replaced warped head. When I picked up my car, the sunroof molding still not replaced, the car stereo I was told they had to order, the sunroof I was told was ok. I worked 2 hours from home making it difficult to make arrangements for vehicle to be left again. When I did call and question the stereo I was told that it had been sent back and the and that they would have to keep it. Again I would have to rent vehicle. The most recent reccuring issue is the ungodly mold smell coming from driver and passenger door, the car cuts out while trying to excellerate onto freeway, pass vehicles, going up roads. While getting on freeway I have tried to excellerate finding myself flooring gas and not being able to achieve more than 20 miles per hour with oncoming traffic, same as going up hill. My paint has started oxidizing in white spots throughout hte vehicle and when I took to dealers 3 weeks ago, explained smell I was told the smell was from airconditioner propably and then asked how many miles I had on car regarding paint. Then aked to come back in an hour. This is after I had called earlier and told to bring in. Regardless of miles it is the same year as every other 2000 with out spots. And it has been kept kept it in my garage since April 2002 other than leaving 2 times a day to pick up child at schoo and occasional road trips. I have been driving a second vehicle. I feel very apprehensive when I go to dealership due to them saying they are not going to do anything. I have sent car in with 2 seperate people getting the run around as well.
