88' sundance efi stalls at stop lights and signs, also when having to slow down to make a turn. seems to run fine all other times.

Radiator cooling fans not working? The ECM is protecting the engine by shutting it down.

wrangler? YJ? 4WD"?
what engine, what fueling system. Carb. or EFI?
2.5 L AMC 150 I4 Complete engine specs[show] 4.0 L AMC 242 I6 Complete engine specs[4][show] 4.2 L AMC 258 I6 Complete engine specs some 87s have a carb. does yours, (nobody can fix enigine not kwowing both facts above and what transmission,.


stalls , moving, only. at stop lights or between gears.
but never just parked idling.
if its random , that would be the EGR valve sticking open.
if EFI , bad idle switch.
if Carb bad dash pot. on carb.

ok and XL 7 but what engine options. gas, diesel, 2L , 2.5L?
what?
and most important , and never ever 1 time stated on this forum
what country.
leaping?

im not sure what you are saying.
it runs ok cold, and as it warms , the engine. it stalls.?
and what does same thing mean.?
my guess, it starts fine then stalls; hot.
but can you save the stall?

stalling is complex. can be many systems in the car.
but can be broken down to :
Ever did the 60k mile tune up,ever? if not why not.
never skip 60k\'s or the motor will run like garbage.


1: lost electrical power. to EFI .
2: bad engine, in that when it gets hot , it loses compression.
3: lost park. 1 or more cylinders, 4 or 6 you never said.
4: bad injection. 1 or 6 of them, flooding or starving.
5: bad fuel.
6:EGR sticking , usually this happens just before a stop sign.
7: if the stall was a bog and the fast right foot saved the stall, easy
the ISC is sticking closed.

when you want an answer, you must include details like make , model year , efi, type of equipment because what you have provided is not going to get a viable response
as posts are not linked , try it again and include the details

Have you tried replacing the O2 Sensor or Mass Airflow Sensor?

Could be bad spark plugs or wires

I don't think a 92 sundance will shut the fuel pump down when the oil pressure is low, but it might. Can you get it to run on carb cleaner. If it is oil pressure, the car should start then run a few seconds and die. Have you checked the timing belt? If it broke the distributor will stop turning which would stop the oil pump.

this may be the cause, try it and see if it helps, it is a very common cause of problems like yours.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

This is a fuel pump issue. i would replace it and the lines as well.also, a minor tune up wouldn't hurt as well. wires plugs distributor cap points etc...

i think your exhaust might have a leak which is heating up your oil when this happens the engine suffocates and wants to die.
