Random 92 Awd stalling issue ..

[Tjsprevia]

I have a 92 previa , she has 260k on her and runs like a top ..sometimes it will stall on the freeway
sometimes it stalls in town , or when parked on a hill .. Or rolling into a turn .. Once stalled she won't start for 5-30 min .. Sometimes it will start back by pumping the gas will rolling in gear .. (Have to be going fast)

Ive replaced the MAF with a salvaged one .. Not it !

It it starts right up if I use starting fluid but sounds like a diesel for a second ..

Oldly ky it seems to do it more often with a full tank !!

Could it be either fuel cut off valves ? Starts easy with starting fluid and if the air box is off it won't start .. ( MAF )

thanks for any help ..

distributor, cap, rotor? distributor o ring? plugs? wires?

distributor, cap, rotor? distributor o ring? plugs? wires?

living on the Oregon coast I thought the same thing ..

I just pulled the throttle body off (pain in ass with those hard to get at violent lines !) the big hole on the right side of the carb was totally plugged with a growth of debris black and rocky jetting into passway.. There was a bit (couple table spoons ) of motor oil in the intake manifold ?

i also changed the fuel filter ...

seems to to be running much better 10 min of driving .. See how it holds up

rotor cap wire replaced 15k ago .. Not by me

well not it , parked it for 10 min wouldn't start , starting fluid work but it sounds like a diesel when it first fires ! Normal?

Still no luck , I took it to 2 mechanics locally, asked one to do an injector clean (he didn’t ) the other said blown motor , but soon realized he never looked at it either .

off to the dealer for an injector clean 175.00:( the van is finally throwing codes , it did this shortly after installing a fuel pressure gauge and driving around..

cyclinders are at 100. 108. 104. 110 which is amazing for a rig with 2900000 miles ..

its not fuel pressure 38 psi-44-psi

starts up with starting fluid ,
seems to die when cruising st lower speeds after coming off high speeds
only does it when warm or hot
will start back up when slightly cooler or after 25 min


Seems like 3 codes popping , I can’t tell maybe I should send a vid ? For help with reading them ?

Thanks for any advise

I was having a simular issue.
My previa has got 290,000kms and was neglected for the past 2 years..
It was having an issue where it would take a few extra cranks to start, and once warm it would idle up and stall, sometimes without idling up. And wouldn't turn on for 5-10 min's.
I did a tuneup
Spark plugs
Cap and rotor ( which was full of oil)
Air filter
OIL change
And this did not fix it
So I took the throttle body out and cleaned it, along with the vacuum lines around the throttle body. I noticed a port on the right side of the intake manifold leads to the egr valve, it was completely gummed up with carbon.
I used multiple picks, carb cleaner and slammed it back together and the idle and die issue has vanished.
Theres also a screw you can take out between the port and the egr valve, that can help you dig out some of that carbon.
There's a good chance your egr vacuum system is clogged and causing vacuum problems

Ever pull codes?
