no need at all for CALIF thermo-probe EGR but does work if installed, sensor there doing zero, both EGR valve work on the FED car, for sure, (do not unscrew the thermo probe from valve.)_
this car is OBD1 not 2,
so you can not use OBD2 anything here, just the flash codes at the DLC jumper
1996 is first care with OBD2. for sure
cat must be installed, and Calif will see its gone at visual inspection. and code 51 tripped.
the dash gauge has not temp marks at all it is just to show gross overheating, and such.
DOES CEL glow key on, and not started, this is step 1 on all these cars this old, ?
lots of reasons to be rich,
thermostat is one, not 190f a 7year life scan part it is. Design life (wax pellet based)
fuel pressure too high
leaking injector. there is only one here
ECT sensor not showing 300 ohms hot with working themostate, higher ohms is cold engine.
spark timing wrong,
bad spark plugs or its wire set .bad (carbon wire suck for life spans, mag core is best)
compression way way too low or timing belt on cam slipped, and compression is horribly sow not 160 PSI but is 100 or less.
that is about it, air cleaner packed in mice nests.
good luck
The CEL only glows when keys are in, engine off. When engine on, the CEL is off. I will check the thermostat and ECT sensor
ALSO - I will be ordering a california compliant CAT from rock auto. is there a downststream O2 sensor that I also need to order? I see an 02 sensor on the exhaust manifold right now, is there another one that goes further downstream by the CAT?
