I swapped out three other FPR's from other properly running similar vintage cars. One was a 3.0 which made it worse. The others were 2.5's. They all do not leak and are in good condition. I did not check the return but I will.
Numbers:
Test 1 AS PURCHASED (HIGH CO AND NOX) STUMBLING ACCEL & POOR IDLE
15mph CO2 14.3 O2 .5 HC 110 CO .55 NOX 1652
25mph CO2 14.5 O2 .3 HC 34 CO .50 NOX 560
Test 2 VACUUM LEAK FIXED (HIGH CO AND NOX) STUMBLING ACCEL
15mph CO2 14.3 O2 .4 HC 103 CO .55 NOX 1663
25mph CO2 14.5 O2 .2 HC 30 CO .51 NOX 571
Test 3 NEW PLUGS, CAP, ETC. TIMING SET TO 15˚(HIGH EVERYTHING) RUNS GREAT!
15mph CO2 13.9 O2 .5 HC 186 CO .65 NOX 2928
25mph CO2 14.0 O2 .3 HC 81 CO .62 NOX 1118
