Compressions/Leakdown Test results

[fixkick]

yes the valves were bad but expected on any car this old.
ok its running rich as a pig. black tip spark plugs
so the scan tool dead. no DTC errors no check engine lamp on key on the goes out running????????????
16v engine the exh man stock loves to crank it does that in limphome mode easy, it gets too hot.
yes it sends 20% oxygen to the 1% max o2 sensors and it slamps to 0v and goes rich.
scanning the ECU with scan tools (real) show PIDS for fuel trim crazy high fuel.
and looping and graphing the 02 front shows it slammed to 0vdc. and does not swing say 6 times a second, that is hard failure for closed loop and the tool shows stuck in open loop. mode OL (not CL)

yes finding good new manifolds is not easy , i got one of the last ones ever. from suz. direct.
is this calif. smogged? CARB (air research board) tested?
if yes , they will reject any aftermarket exh manifold that is not CARB sticker certified.
but no state told and matters huge on cars this old
my 95 jeep is free of smog tests in TX.

the cat on the 1996 is called 3 way cat
and the 02 must work and swing correctly
and EGR must work or NOX fails.
28 year old cars many states do not do smog tests after 25 years old, so few left running it is not on theIR RADAR.

you can even drive the car with 02 front pulled and see it go way leaner and MPG goes WAY Higher.
UNPLUGGED IT FREEZES AT 0.45 VOLTS AND IS mid point.
hey good luck to you, hope it gets better soon.
