Hey, So I have a 1998 chevy silverado with the 5.7L and im having a problem with a misfire on cylinder 1 and then having constant spark on cylinder 3 any Ideas on this problem I have replaced a lot of parts trying to chase down what's causing this problem and could use some advice if anyone has ideas please let me know Thanks, Corbin

 

please list them, and whether they were OEM

 

So I have a 5.7L there's a misfire on cylinder 1 due to dropping spark and there's a misfire on cylinder 3 with constant Spark no matter intake strok or exhaust stroke

 

Don't multi-post, please. Thank you.
