1980 jeep shuts off at a complete stop
no jeep stated,
which engine, and is the carb setup still stock?
and never started again, or started after parked 5 hours and runs perfect other wise. (my other shoe dropped) hark ?
engine not totally dead,? what?
that is called stalling
what is your question you never formed one.
why, , it stalled.?
why did it stall , then engine is misfiring or the ISC system is dead.
how to diagnose it? (i can go 10 pages, must I? can do. ask)
who can fix this: any ASE shop in USA can.
would some one guess? sure, never tuned up this decade wins all bets. most the time...
guess 2 (most guessing is useless) the EGR stuck open.
my guess it just stalls at stop lights. but runs perfectly????
can you prevent the stall with fast right foot actions
this answer is key to solving the riddle.
and how hard was that, if yes. key 2 , very imporant
2: tad hard but can.
3: had to wot the sucker to keep if from stalling, WOT = wide open throttle.
there are many tests, to solve this, got tools? meters?
we cant guess any of the above. eva.
it can be bad fuel in take, or carb fueling wrong.
it can be carb messed up
it can be bad spark
or even a bad engine, and i never fail to test engines first for compression , for sure a 1980 as i dont like spending cash tuning a dead engine. (parts and labor worth more that car.... economics)
carbs are tricky,
is the chock stuck on all the time?
is the float lever holding and at spec, if not fix that now.
are the jets clean, and all nozzels and emmusion tubes in carb clean.?
got vacuum leaks?
these carbs have dash pot devices that prevent stalls when you cut the throttle in DRIVE (is it a/t or m/t box) vacuum operated it is.
is M/t box does it stall if you push in clutch or pop it to neutral?
