Ignition or fuel 60PSI doesn't mean the Air fuel ratio is correct Check the ignition coils measure resistance or just change them out after all these 14yrs.. how about the HEGOS when was the last change?etc MAF dirty? TPS, throttle body clean up..spark plugs.

Check the spark plugs & wires, make sure they are working properly. Check the compression in the cylinders, make sure they are all relatively even. You didn't leave much info, but if you're blowing blue smoke out of your exhaust at high RPMs, you have a bad cylinder.
