bucking, stalling, but only on the highway
This just started over the last few weeks. Street driving is fine, good idle, good acceleration etc. Get on the highway and about five mins in she starts bucking, loosing power, small pops. Pull over, starts right back up, runs fine for a bit then does it again. Generic Holley carb on a 78 Jeep Wagoneer 360 stock w/auto trans. Any ideas?
