Question about 1990 Suzuki Samurai

1 Answer

1990 suzuki sierra - stalling,

Had a problem with revs dropping whilst driving and almost stalling but never actually did stall. Had the car serviced and was told Vacuum advance unit needed replacing did that and it appeared to work for a day or so. Took for a long drive and car started stalling, was told a fuel jet on carby blocked. Had a mechanic look at it and clean out carby but still stalling intermittently. Have been advised to have carby reconditioned. before spending a lot of money on this any other ideas as to what the cause could be. The mechanic who looked at the carby now thinks that maybe it could be something to do with the accellerator pump? Sometimes the car runs perfectly, other times it doesn't. Other possibilities are the Choke?, Leads to coil? No one seems to be able to find the fault do you have any ideas. Also recently fitted a Snorkel could this affect anything.

Yes your snorkel should have the right size for air to come-in, hope you have the right diameter, but snorkels will not seriously affect your vehicle substantially.
It could be that your fuel system is dirty. I would go for having those carbs cleaned but before you do this, I would advise you to clean your gasoline tank of rusts, water then blow those fuel lines with air to declog, change your fuel filters, if you do a lot of offroading, put two(2) fuel filters, first filter goes just above the gas tank, beside the chassis, the second will be place before your fuel pump, inside your engine compartment. have those fuel pumps cleaned too, check for leaks and moistures on your fuel hose and lines. if you have done all these, and nothing happened, check for strong sparks on your plugs, it could be that they ready fouled up.and check on your igniton coil,

Car stalls whether its hot or cold when the throttle is flicked down or you rev up and leave it to drop revs then it stalls.

Is the engine idle just set a bit low anyway? Can you access the idle adjustment and turn it up a tad? The sluggish drive may be in need of an engine service but a 1.3 is small for this car. Check out online car owner forums to see if others think so to.

i feel your pain, carbs are fussy things..
for sure if the engine is health and the distributor is timed
right and advances by the book , does it?
then its a bum carb.

the problem with is fixing a 27 year old car is probematic.
back when, we can just buy a rebuilt.
or buy a kit.
we'd clean the carb , then kit it and then retune it.
now the symptoms of a bad carb,
1: it's lean.
2: what causes. lean
a: float level too low. RTM read the manual look up level spec.
b: air leaks. any where in the intake tract.
c: clogged gummed up jets, for sure in any 27 yo carb.
d: clogged nozzels
e: air jet fell out and not is tool lean, (emulsion jets)

above is for a hot motor.
if motor actually gets hot.
if the car stalls cold.?
then the choke is bad.
how do you like my carb in a nutshell post.

Suzuki Grand Vitara 2.0 litre petrol. Starts from cold (stood overnight). Twelve minute drive to work - slowing down at lights etc engine stalls constantly. No problem re-starting. Pull into a layby...

Same problem for me. The car would idle at about 2500 when started from cold and about 3 miles on would not idle at all, resulting in the revs dropping off when changing gear or stopping. Also rather jerky in top gear unless thrashed - numerous trips to the garage for air idle valve, injectors etc. but still a problem! Have just found out that GVs are a bit prone to carbon build up in the throttle body - mine was almost blocked - it now feels like a different car.
