Fueling up? Running rich? As in way too much gas? You should have some codes present if your air intake system has a problem. I would check the codes first. Is your air cleaner clean? Nothing trapped inside the air intake tube? Butterfly valve operating properly? Vacuum lines all connected and not leaking anywhere? Do you have spark? Check timing, check ignition module, but check codes first!
Hello
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 SPEDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
