Did my knock sensors need to be changed on my 92 Buick Regal?

Asked by May 22, 2013 at 02:42 PM about the 1992 Buick Regal Custom Sedan FWD

Question type: Maintenance & Repair

I have. been trying to keep my car running (without getting hit by another car).  When decelerating around a corner,, at a stop light or sign etc. my car just loses power.  So far I have been told get a oil change (tune up) done, replace fuel pump and filter done, replace spark plugs and wires, done, mechanic said my motor mounts were broken (which they were), said they needed replacing as well as knock sensors.  I drove away and stalled and was almost rearended by a semi.  Today took it back and was told the wires to the sensors were fried and needed replacing.  My question, did I really need new knock sensors???  Why did the mechanic not see the fried wires yesterday when the new sensors were put in?  Is this going to solve my problem?  I am slowly going broke trying to get my car going over $1500.00 into it now???  Please could you advise me before I head back to the shop.   Thank you so much for your assistance.

Probably not. But not sure what codes he found. I'd have another mechanic look at it if your still having issues.
