Shuttering/vibrating issues

['95yellowGT]

my car runs fine....most of the time. My car has started doing this shuttering thing after it warms up while just cruising almost like its hesitating like its not getting gas at times. It feels like its down in power while its doing this. It will also sometimes at redlights or stopsigns act like its goin to cutt off but then it revs back up. What could this be? plugs? coil packs? any ideas?? thanks guys

Here's an idea: perform a thorough visual inspection of your shuttering Cobra and repair any faults you see as necessary. Next, plug in a scanner to see if any codes are present, if no codes are present, access the Parameter identification data in the PCM for the fuel control system and monitor the voltage values for all the sensors along with the percentages for fuel trim, load and barometric pressure. Unless you don't know your head from your ass and you can figure out if the numbers flashing onto to the scanner display screen are in the ball park park or not, you should be able to narrow the list of possible problem areas quite a bit. Good luck.:-D
