I have dropped 2g head, including intake, on my 1g 7bolt block recently - '94 Talon, non-turbo, most likely w/ California Emissions ECU settings . I have also installed the 1g CAS, throttle body and EGR valve on the 2g head; among others. The timing of the engine should be 5 degrees BTDC +/- 2 degrees. Mine is 2 degrees BTDC since I ran out of travel on the 1g CAS while setting the timing.
I drove the car for the first 50 miles w/o any CEL. After about the first 50 miles of driven distance, driving on hwy at cruising speed, the CEL came on - veeery slooowly, as if hesitating. It did not flick on. There was no indication of misfire nor any other engine irregularity that I noticed while driving it. The engine runs fine. And now the CEL stays on - of course since I did not clear the codes.
I checked the ECU and pulled a diagnostic trouble code #43 out of it. My manual tells me this code is generated any time there is a problem with:
1/ harness and connector
2/ EGR temp sensor
3/ EGR valve
4/ EGR solenoid
5/ EGR valve control vacuum
Given that the code #43 did not appear immediately after I started up the engine, my suspicion is that the problem is #5, valve control vacuum, but don't know how to confirm it.
There were no problems or code #43 calls with the 1g head on. This problem appeared after the switch.
Before I get into any of this testing:

would you gents know what my problem might be? thank you.
