2006 STS Cadillac - 51,000 miles - I bought the used vehicle November 2009 had 40,000 miles at the time. Car broke down last Friday: Tuesday - Mechanic believed it was the crank sensor Wednesday - Mechanic solution car not firing replace all six spark plugs and see if car fires. Thursday - Mechanic tells me engine is done and need to replace.. Any insight would be a greatly appreciated.. Thanks.. Kip Koszewski

I hate to say this, but I think he don't know what hes doing, what needs to be done before any one can say that an engine is done, do a cylinder compression test, that will tell you the condition of the engine, sound more to me like elec., when you say not firing, do you mean the spark plugs are not getting any spark?

Yes I will ask for a more detailed diagnosis Friday and supply you with feedback! Also said the engine was burning oil quickly but still had a quart and half left.. I am perplexed...


Thanks and have a great evening...
