I have an 87 broncoii that sat for about 4 years and I recently got it running . When I'm idleing it runs like a champ but when I drive it starts to choke out like its struggling for gas. I drained the old fuel from it and ran fuel objectors cleaner through it but it just started acting funny again. Anyone have any ideas to what the problem might be

Replace the fuel filter

I did that allready and it still struggled

just try an run in out for a coulple weeks. mine did the same shit but it just cleared out
