|  '84 Cross-fire engine
My engine shakes around 50mph. Feels like it wants to sputter out. I was hoping somebody could give me some ideas to what it might be. Thanks, Chris | ||||||||||||||||||||

Not on so little data. Pull any codes? Check spark? Check fuel? | ||||||||||||||||||||

It started it just didnt stay on until i changed fuel filter and pump. I dont think its electric. i have a feeling it is either gas or air pathway.
