The problem I'm having is that when I start the engine, it runs awful for the first minute or so, it stumbles and sputters and wont stay running unless I have my foot on the gas. Then after a min or so, it just starts running normally, it's almost like someone just flips a switch and it runs fine. It's not a gradual change, its instant. I've checked for vacuum leaks and loose connections, but haven't found anything, and I'm not sure what I should check for next. I recently dropped the gas tank, had it dipped and re-lined and installed a new pump and filter. Any thoughts or suggestions would be greatly appreciated.
