Question about 1994 Buick Century
I have intermitten hesitation that occurs once every two weeks. The problem only occurs when the engine is in gear. Most recently while going up a hill it stumbled almost to the point of stalling, I put the transmission in neutral and it went away, placed the transmission in drive and started hesitating/stumbling again. Then it cleared up and I drove home with no problems. I have replaced the fuel filter, spark plugs, air filter, conduct oil changes every 3000. Currently have 53,000 miles. Conducted engine scan, no codes. Operational analysis values were normal. Continues to maintain 26-30 mpg.
Possible cause/solution of hesitation/stumbling?
Seems as though you've got it covered...Try adding "SeaFoam" ($9) from Advance Auto Parts and add it to your gas...drive for at least 100mi. Good Luck

Tips for a great answer:
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems 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. Also always check fuel pressure for correct spec for your make and engine type.
