Trying to narrow down the culprit, happens everytime i drive the car lately, running at cruising speed 65-70, and even lower speeds like 55, the rpms will go up and down about 2-300 rpm without a throttle change.

sometimes when i first start the car it will bust off and stay running other times it shuts right back off!

I`m leaning towards the fuel pump, the filter is maybe 2 months old.

What are some of your thoughts?
