Question about 1995 Buick Regal
I have a 95' Regal with the 3.8 L, normally runs great and would shudder only occasionally while excellerating or on cruise at about 2000 rpm, recently when the engine gets hot (after approx. 15-20 min. running time) the check engine light will come on and the car will hesitate or miss slightly under accelleration. It almost feels like it is being starved a little. I have already replaced the fuel filter and O2 sensor 1 and still no change. I have already had the transmission checked and it is ok. Where to next?
I had the exact same problem. The mechanic found a spark plug that was leaking on the back of the engine that was a pin to get to.
He replaced all plugs and wires and I no longer have this problem, so you may be onto something with the plug wire being loose.

If you look under the cat. converter there might be a plug that you can remove to clean it out with.If you remove the plug then just rib - up the engine a time or two .That will clean it out for you.If the code that Auto Zone pulled up was PO420 then you might start by replacing the 02 sensor that's right before the cat. converter.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
