The easiest way to really find out is to get/borrow a wideband and see if you're actually running lean in the upper RPM range. Other than that, I think you're going to end up driving yourself crazy trying to come up with different theories.

 

UPDATE!!!!!!!!

ok,i order new adapters from StephanMax(thanks alot) installed them,set the timing and reassembled the timing cover started upand for some reason, cylinder number 2 wont fire. ive swapped coilpacks,sparkplugs and injectors, check the constant and signal wire for the injector and coilpack and the grounds. everything is fine and working but its misfiring and when i pull the connector for cyl 2,it doesnt fire.

is this cam timing related or ignition? plz let me know someone

 

try swapping the coil pack into another cylinder, see if the problem moves.

 

i did, stsyed at cylinder 2

 

What engine management are you using if any? The coil pack may not be getting the ignition signal if there is an intercept such as an engine management. I know i had a bad plug on an emanage blue ignition harness that had a bad connection that would cause a misfire.

 

Then it's time to have some fun with a multimeter. You either have wiring issue or a bad ECU. 99% probability, it's a wiring issue.

 

ok,so if it was a timing issue,it would be more the 1 cylinder off?

 

im not to sure thats its wiring or ECU because while running,the injector constant and singal both get 13.8v. the constant and ground on the coilpack put out 13.8volts also and the signal was putting out 150-170mili volts jus like the other cylinders.
