Car almost stalls out- like gas is not getting through the line. I had the oil changed- fuel system cleaned. It was fine for a couple of days but now the light is back on and it sputters at a red light. 77, 000 miles on the car

Re: Engine light comes on
You need to check the fuel pressure, and also was the fuel filter changed? Another part that will cause this is what is known as the Mass Air Flow Sensor, it is located in the rubber air intake hose to the engine, it has a multi-wire flat connector (gray or black) going to it, a quick way to check proper function it is to disconnect the wiring from the MAF sensor and drive the car, if the MAF is the problemt the hess. will go away, this will cause the engine lite to come on and is onyl a test, you will need to replace the MAF (Mass Air Flow Sensor). One other question when you say the light is on, is that the check engine light? if so is there a trouble code stored in the power train control modules memory?

There could be some water in the fuel (especially with the weather we are having) and it wouldn't hurt to put some Heet (Heat) in the tank. It is designed to remove moisture from the fuel and can be purchased at nearly any retailer. Even if your 'service engine' light isn't on, there is likely a code stored in the 'pending' section of the engine computer. Places like Auto Zone (in most states) offer a free computer scanning service. Ask them to test it and if they get nothing, ask them to test the pending codes. If you get any codes, have them write the codes down so you can post them here for further explanation. Don't let them sell you anything. Most of the people working at stores like this don't know what they are doing and rely on the computer to tell them what to sell you.
It could be a clogged oil pickup or the oil pump may be not supplying enough oil pressure to the engine, causing the engine to stall. I would have the pressure checked to see if the oil pressure is within specs. Maybe a new engine oil pump will be required.
The temp. of the engine may have to do with the coolant/antifreeze system needing to be flushed, or the fan not turning on at the proper temperature.
If the fuel filter were clogged, I would think the car wouldn't run.
Have the codes for the engine scanned with an obd-II compliant scanner, in order to determine what other problems may be present.
.A}.could be the fuel filter ..B}.converter is plugging up .C} a vacuum line has come dry-rotted and or is come unattached and is sucking air .D} .idle speed is too low ..E}.The firing order is incorrect ! ....F}.clogged air cleaner ? ...G} check all fluid levels for proper fill levels . or it could be the choke sensor ids sticking or faulty ....have you tried running any fuel injection cleaner and a good grade gas this is just a minor list of points to start with after all we all get bad gas sometimes .
You describe a symptom that most often is related to malfunctioning / failing Throttle Position Sensor. Check engine codes and reference them to a OBD II code reader, you can use a inexpensive code reader from a Discount Auto Parts store... If code references TPS sensor replace and reset codes... hope this helps...
