drive with the jumper in place, the DLC, jumper called DIAG.
see if it throws codes, driving , the jumper is pure harmless. same on new cars x10 better, and still a valid test.
there are many tests to do, to fix any car for drive-ability symptoms. (poor)
first are basic engine tests.. after all EFI can not run a wrecked engine, it can do ok on a weak engine, but not a wreck by wreck i mean loss of all compression on 1 more cylinders.etc
seems to me its running real rich, and when cold rich added to bad rich give syou what?, way TOO RICH, and misfires more....
if engine is good, and cat not melted.
it's only these caused. (mostly)
1: bad fuel.
2: injector 1/2 clogged. up ,clean it? Bogging it will.
3: low fuel pressure. (will bog) not misfire but BOG ONLY.
4: bad map sensor. (lots of ways to fail, even the hose to it blocked with crap or inline filter to it packed in junk, or hose leaks)
5: BAD SPARK. (CAP/ROTOR/HV WIRE SET/PLUGS, GAPPED TO .028INCHES NEVER AT .045" AS ALL COME NEW IN THE BOX, GAP THEM OR IT WILL MISFIRE HORRIBLY.!!!!
spark timed wrong, did you even check this yet?> using a $20 timing light with the freeze jumper inserted? at 800 RPM hot, can I presume it even holds 800 RPM hot, AC off?
6: ECT DOES NOT READ 300 OHMS HOT. A HOT Engine remove ect wire plug , ohm meter at (DMM) to ECT sensor pins, 300 ohms, (0.3K ohms ) if this is wrong the thermostat is bad, stuck open
we use and IR thermal gun ($20 tool) to see omg that stinking rotten(failsafe), thermostat latched open, gee get rid of it, never use those ever. 180f good. not below, 170 hot
the IR gun reads about 10f deg, lower than what is on the inside of the thermostat housing.(gun pointed there) fully hot engine,
If water is 180f or more and sensor not at 300 ohms the ECT is BAD, No not dead, but bad, its now no longer calibrated and at spec, its BAD. it has 2 pins not 1. 91+
the map readings are on my map page, type map in the search box. we use a voltmeter to read the output, keyon, idle and WOT for 1sec)
http://fixkick.com/
is idle vacuum steady, hot, 19" of HG on the gage (yes $20 gauge)
is the engine misfiring?, do you know how that sounds is is felt, its not a hesitation only, its heard too. and felt, (a short hesitation only is a whole other problem set)
does it misfire under load, up a hill say..... ever heard a chain saw misfire?, that un even 2stroke beat of the exhaust note?
that is misfire. classic, and is major symptoms,if present. in any driving mode hot.
does the engine misfire or only bog going up a hill wide open throttle. held.,
misfire is violent.
bogging is like dragging heavy boat up that hill, or a 2000 pounds dead weight.,
i cant drive your car, so words do not tell me how it drives, words are weak, (not yours any words in any language weak on engine performances...)
ever consider a new O2 sensor,? sorry if did already/
the old 8v loves to go super rich with a bad 02 (this is by design, not accident, this is Bosch's fail safe rules) (the sensor die and ECU goes rich,on purpose , rich is safe, lean bad burns valves)
you can even unplug it to see car run better if the 02 is fibbing (did you?)
the 02 loves to lie if there is any form of exhaust leak near by, like the exh manifold header gasket bad, sucking in fresh 20 % atmospheric, air, between each PUTT.!!!!
yes IT CAN SUCK AIR THERE< for SURE. (ask , we have nice pressure plot to show you)
unplug it. that O2, as a test...
this ECU is Dumb and Dumber, just like the movie... it's brick stupid , in our modern world,there is ZERO "AI" inside. (my jeep has over 200 DTC errors , by comparison. )
the 56b30s series of ECU have great limits, one is the 02 sensor reading wrong allows the ECU to inject way too much fuel, (corrected in USA in 1996) T
This ecu love to burn CAT up, red hot and melts them, it loves to...
the same ECU can get lost. and not post any codes (gee it is stupid so.... cant fix stupid as they say)
the same ECU will never tell you if a sensor reads wrong, only dead sensors are reported, unlike new cars.
let me explain lost.
The ECU does not monitor spark for misfire ever, until 1996
so that means if it does misfire, the ECU does the wrong thing, it adds fuel, ( we used to say leaning in to a left hook, boxing, yes dumb....)
yes this is a stupid act on the ECU part but is REALITY.
the 02 measures oxygen, not fuel! so makes gross errors during those misfired air slugs passing by at each and every misfiring spark plug going down stream now..
The ECU gets lost other ways, too.
if it tries to add fuel and runs out of trim range, it does not report it, like 1996 and newer cars do...so well.
so it slams rich and is happy there, but never us.
that is about it.
tell more about bogging and misfire.
elaborate all that fully,
bogging with misfire is just misfire. All misfires reduce POWER< all do. and wastes tons if fuel doing so.
bogging only is bogging, (means lack of fuel) in most cases no loss of fuel due to you can never go fast enough to burn it. (in your mind imagine a 1/2 clogged injector) and be here.
or fuel pressure not in spec.
Misfiring is violent, is your car misfiring.?
we can start there, really.
