1999 Suburban
Good morning I have a 1999 suburban with a 5.7 Vortech l. Looking for some insight as to the popping and back firing that I'm getting while driving down the highway at around 1800 rpm . If I'm cruising around 50 to 55 miles per hour and I take my foot off the throttle and lightly press back on the throttle the engine pops and backfires any idea where I can search for the problem
