Think one of the injectors may be taking a ****. Car finally ran on all 8, and ran strong for about 10 miles. Then one bank started running leaner, and the other bank rich. Has a definite stutter, like one cylinder is't hitting. Spark is good, and NO codes. Maybe an injector? Is there any way I could test? Or is there a better way to determine what's going on?
Also the fuel solenoid on the wet kit appears to be leaking a drop every minute or so, related? What about the AFPR?
Sorry, just not familiar with this engine whatsoever.
