I have a 1992 LS400 with 120k miles Garage Kept, Drives Beautifully but just last week it started running like a peace of crap. Its now shaking very bad when i drive and has a loss of power, and there is also a loud banging noise under the hood. Now it wont start at all!!. I took to an area mechanic who charged me almost $200 just to tell me whats going on and then said he couldnt fix it. He said my #1 Cylinder has no compression, and Cylinder # 2-&-8 have bad injections...In the lamest terms i have no idea what this means, He said i may be looking at replacing the engine which really blew my mind because it only has 120kmiles, and before this problem my car drove like new, with no indications of any problem...and im really not in the financial standing to replace the engine...Does any one have any suggestions to my problem???
