Misfire, but no DTC's?

[Fabricator]

welcome,
nice data !, but only 1 parameter in this xls file can I figure out RPM in red.
are you logging metric,? where is ECT data in C" 90C ? line 9 ECT? Sorry - all values are metric. Line 8 is ECT

id need you to put each sensor name for each line, and some are trim, i see. I attached the same Excel file in an older version - can you see the sensor names in there?
yes, many DTCs are 2 or 3 driving cycles, but pendings , are limited to 1 at a time. so weak that.
the numbers matter in the XLS but no index to your list, at all, sorry.
my scan tool the PARAMS , i can log in any order or sets, so the order is never the same tool to tool , must be known first. (names)_
compression good
vacuum good, but does the vacuum read correctly when throttle gunned, (i bet it does with new cat) not melted. I do not have those numbers - what is desired when throttle gunned?
fuel pressure are ok , if you gun engine and pressures stay over 30 and up to 40. Fuel pressure was 43# when misfire was happening
if the maf reads ok, seems to me the injectors clogged from bad gas. PO said he replaced injectors - will check if old ones were reinstalled
is ECT at 180f to 195 hot? 181 to 201 F hot
if maf is ok, and the fuel pressure builds off idle (gunned) seems it does, so the injectors are packed. (make sure all 4 are noid tested and firing)

ok i just uploaded what you said is missing in books, sure store rag books sux sure, chill-tons, HAY-Wired (haynes)
sure.
but the real book is full of all DTC info... each test if fully defined, and is here.
as of today , put there in post 1, ack-faq.
here it is ( best EFI pages and engine manual) see part 1, 2,3,4 those are all DTC fully documented by suzuki then reprinted by GEO.

I say clogged injectors.
pressure fuel ok, MAF not dead,
the maf works in cold start, so if good , no 02 sensor needed for cold and WOT.
if the injectors are clogged many report the MAF unplugged adds power, well sure its in limphone goes super rich and can hide 1/2 clogged injectors to a limited amount.

yes p0300 is all cyl, misfiring but will not set in one drive. but you hear it missing so... we know it is. I will try to post video of misfire for you
all spark parts new> (is see full tune up below but not plugs? gaped to 0.028" never use out of box gap it is always wrong.at 0.045" says NGK Plugs were in good condition, but I gapped all to 0.028"

or bad coil. inside distrib,
wish i could see each line 5 to 23 names? If you cannot view PID names in attached file, let me know and I will list them

if the injectors are clogged, we can prove that , with propane gas. not LIT. feed it a snort of propane gas in the intake at (IAT sensor port?) on air cleaner box. and see if it wakes up, at the BOG point, if yes, injectors are clogged. OK

( a normal propane nozzle, unscrewed and host attacked works same as this OTC tooL))


the MAF can be tested with a voltmeter, on the output pin easy. type maf in my fixkick, search box. super easy testing MAF Will do

Thanks for all the great info!
