I've been trying to Google this for the past 30 minutes or so before someone mentions that. I've found a few but people just seem to be chasing their own tails. It's a 302 4 barrel in am 85 f150 but the motors an 87 mild cam. So I was listening to her rev at idle. Had it at about 1500 holding steady, went to raise it feeling for 2 k rpm and it starts to cut out I held my foot steady and it stayed shitty. Went to increase climbed rpms very badly same problem up to 3 k ish rpms then it smoothed out and climbed just fine. Went to replicate the results but this time I went straight for 3/4 throttle it took a second to get out of the funk then climbed like it should. I'm leaning towards fuel pump issue or possibly vacuum leak. What do you guys think? Thanks.
