Misfire, but no DTC's?

[Fabricator]

ECT 94C why so hot, ?201.2F is HOT, max hot thermostats are 195F, 180f is stock. so 200f is wrong or ECT is bad.
thermostat bad/wrong, radiator clogged. fan clutch dead/ or some other cooling system issues,? this is a problem but not THIS problem.

Will check t-stat and associated cooling system as it seems to take awhile to warm up too...

98kpa , is 1bar/100kpA is WOT, very near. so i see that. frame 16 (gunning throttle sure)
frame 16, only 1300 RPM, so that is a huge bog? super bad engine power. Frames 15 & 16 show data when misfire is taking place, hence 93.3 TPS to make it happen
vss = 0 means , car is parked, or VSS bad. moving, Yes, car standing still

spark advance , OK , 8 TO 42, In park or neutral advance is very aggressive due to no engine load. here. normal.

TPS 93% or WOT. good.
02 off line, frame 15/16. is normal, in Openloop , wot is always Open loop. and is normal OK

MAF shows 2 to 20, and 20 is way less that 55, but MAF is a chicken and egg thing,
( if engine bogs 50 can not be attained.) can be for engine,weak,or cat clogged, weak maf, weak fuel pressure (not you) or in limphome)

conclusions,
MAF weak.???????????????? why? , no vacuum leak can cases this unless maf not present in many induction tube. (stock induction?)
see my rules pages below. PO said known good MAF was swapped in while troubleshooting, made no difference - old MAF reinstalled


CEL lamp off ,in all data seen in XLS? CEL works key on and goes off after start
the canada car (not factory CAMI ) but sold to citizens of this country has no CEL for misfire. (MIL dead)
proof. (silly of them to do that but they did) (hood sticker tells you if car is USA EPA or canada (oakleaf, smog car)

list of DTCs that can cause, limphome, I and to dig this out of the 4 long chapters posted above(PDF) 10 years ago did that.
your 96 the transmission has its own DTC connector under steering column
MAF = P0102/103
IAT = P0112/113
ECT = P0117/118
TPS = P112/123
VSS1 = P0500 ( speedo vss) Vehicle Speed sensor = VSS (moving only)
(97+ and newer only do below) P07 means 4speed box.
TR = P0705 (A/T Range shifter output in conflict) (gear shiftier switch LIES)
VSS2 = P0720 ( 4sp Vss tail speed sensor dead) , moving only.
SS#1 = P0753 (shift solenoid 1 bad)
SS#2 = P0758 (shift solenoid 2 bad)
TCC = P0743 (torque converter clutch malf)

the transmission must be scanned too. if 4speed, is it? Trans is 5-speed(?) manual

back to maf againl.
see me hit 55 on my maf? I plotted this is Excel. then. TPS over MAF. simple but very effective. (but maf only can be tested this way with good engine good injectors and full fuel pressure)

if the engine can not make power, the MAF will show weak even a new MAF, due to air flow IS WEAK (if fuel mix goes weak the maf will show weak)
I then took the maf off the car and used my vacuum cleaner. and got 3 volts output on my MAF, a leaf blower would do more. 4v?
due to one guys car was weak MAF but really was not. (his was fuel pressure low, or injectors clogged.)

is CAT plugged up? if vacuum looks backwards gunning throttle or bounces VACUUM is wrong and if queer odd , vacuum inversions, CAT IS melted.
but is new CAT so is not Cat.
ok so far we have these facts.
