cutting out under 3.5k

[sandman315]

hey whats up everyone, first time poster, long time reader, ive had my suzuki sidekick for a couple years now.....always kept upkeep a prority.....well the other day i headed out for the night, stopped at the gas station...went to my buddies house to play cards.....she sat for like 30 minutes, i hopped in her and pulled out of the driveway, and she was cutting out under 3.5k, it just stumbles no power, but the second you hit 3 and a half rpm she takes off......its a 1996 sidekick sport 1.8ltr, no codes...ive read it like 4 times hopin for a code......any help would be great.....

ouch no codes.
this is a cop engine and will set code 300 and 301 to 304
and chain driven cams DOHC.

if you have a full scan tool not a coder reader ,you can see , pending codes.
ones the almost set a DTC but not.

you can see , all sensors in real time.
Map ,maf , ect, iat, and fuel trim.
if one of the sensors is buggered youd see it .
on can rent such a fine tool at most auto stores.

if that isnt your style.
you then need to find out is it Spark or is it lack of fuel.
on this COP bests (coil on plug)
id leak in some propane while driving.

buy tool , make tool.

any cheap , propane torch can be rigged to a tube and this tube snuck into the engine bay, and then plugged it to the evap main nipple on the plenum

i can show you a drawing of such vac, nipples,
you then drive and when you get the bog, feed in a little propane.
power comes back it is fuel starvation.

sounds hard to do and is not.
but that is why they have OBD2 on your car so repairs are vastly easier.

cheers.
I presume car has new plugs , and gapped to factory spec.
and no engine modes.
