1987 190e 2.3 again

[kmaysob]

hello all, i posted a while back about my mothers 190e2.3 failing emissions. the last readings were hc: 03.90 std is 1.60 co: 089.01 std is 15.00 co2: 229.20 and nox 00.33 std is 2.50

i put new wires,cap, and rotor on. the plugs were done a year ago so i didnt see a need to change them. plus they looked good. the cat was bad so i also changed it.

today i took it through emissions and it failed again. hc: 3.90 std is 1.60 co: 77.07 std is 15.00 and nox: 0.61 std is 2.50.

so the hc and nox went up.

i did a compression test and heres what i have:

cyl 1 150psi
cyl 2 125 psi
cyl 3 120psi
cyl 4 125psi.

the compression test was done with a warm engine so im guessing the numbers will be lower once it cools.

can anyone help point me in the right direction on what to check?

any help would be greatly appreciated
