It's me again... My 5.7 was misfiring and blinking the engine light, put plugs in it and now it pops a bit, not like plug wires are not right as it runs "ok" feels sluggish and hard to start, dies sometimes when going into gear. The plugs now make it pop all the time but not as loud as a backfire....pulled the cap off and it looks a bit crusty not too much so I took sand paper to it for a few minutes and it didn't change nothing. Seeing what I should try before I fire the parts cannon
