try pushing the 5th and 6th port actuator arms down, the actuators or sleeves may be stuck. also do you still have the stock main cat?

There's a chance it could be a clogged exhaust... but usually it's the Cat's that clog - and im assuming you don't have any of those.

JUST because you got the injectors cleaned..does NOT mean that they are squirting. Refurbish your stock ground points! Sand all metal surfaces, and ground wire o-ring connectors. Make sure the ECU ground is bolted down...(underneath the intake manifold, bolted to the ?rear? housing..2 wires.
