I have a '89 350 Tune Port and am having problems with the engine sputtering with I just feather the throttle at any speed. It feels like the engine is not getting gas for just a split second and then kicks back in and then does it again and again until I give it more gas or let off completely.
I have been told that it might be the Mass Air Flow meter or even the Throttle Position censor.
It happens more when the weather is hot, always happens at least once a day.
Any thoughts???
