Car will start up but shuts off while im stoping
no year?
which engine option? (size and cylinder count)
starts and runs hot or cold, or only fails hot and only stopping?
on newer cars, it has IMMO, (immobilizer) and does that, if the IMMO
is unhappy, it thinks you are stealing your own car.
it has a light. is it glowing to warn you, that it is ACTIVE?
if not IMMO its only (LOL 1 of 4 things ) (50 causes, but 4 groups)
to find it takes a simple test,using simple and cheap tools.
1: loss of 12b DC power. to the EFI system. (no spark or no fuel)
2: loss of engine compression.
3: lost spark , (do a 60k tuneup now,)
4: bad fueling.
the other causes of stalls , are EGR stuck wide open, the tuneup
this is listed, as, check EGR , we check it and clean it.
the iSC is sticking closed, this is the Idle speed control.
I just clean it and make sure it works.
in fact during a tune up, sparks, filters, we chean both the EGR
and ISC.
now the simple test of all just before it stalls
can you save the stall with a fast happy right foot.?????
the answer to the can really help
as can what do the dash lamps do, just before stall.
if car has dash voltmeter, that one meter solves #1 , in a heart beat.
