Jacob and Nickolas,
Here is a list of the work I've done:
New plugs and wires
Cleaned the MAF
Replaced the inlet plenum gaskets when I did the plugs
New EGR Differential Pressure Sensor
New cam shaft synchronizer ( did not replace the sensor )
The problem with the at speed surge is still present. More pronounced with the A/C is running
Need some suggestions on where to look now. I am out of ideas. I did notice the the PCV valve is very loose in the hole it sits in but not sure this would cause the issue.
Any ideas and I am all ears.
Thanks in advance.
