Hello My 1998 suburban has a 5.7. Just replaced engine and now less than 600 mi. It is dumping fuel into cylinders. Locks it up had to drain fuel then starts multiple misfires code. It has newer spider could this spider be defective? Any suggestions as to what controls this type symptom. Do I need dealership to test? Mechanics here are seeming to have a trouble diagnostic.
Thanks any info would help.
