Those manifold nuts should be tightened to 18 ft lbs. There's one under left side the air flow meter housing that you probabaly won't see unless you remove the housing. There's 3 nuts holding the air flow meter housing on and 6 injector lines need to be undone to move it.
The plastic injector blocks often crack and can warp a little after a while. If they need replacing aluminum ones are better. You can get them from Turbokraft.
Check and make sure your AAR is getting 12 volts to the plug when the rear fuel pump is running.
