My car sometimes dies when i come to a stop sign or intersection unless i keep my foot on the gas and 1 on the brake.

I have seen this symptom and it is caused by a leaking power brake vacuum booster, when you apply the brakes it creates a huge engine vacuum leak and this causes the engine to run lean and rough and die in some cases. Most likely the shop was looking for an engine issue when it was a brake related problem

If it is a caburetor vehicle setup carburetor, if it is electronic fueling , check module with a code reader.

intake idler unit needs cleaning unit is on the side of the intake not the one that controls throttle the other one. remove and clean out. or spray carb cleaner in to clean out. also clean the connectors on the wiring. should be fine after that, if not you will need to remove it and give it really good clean out.

You don't say what year or engine. but I would try checking the idle stop solenoid and the choke adjustments. You give more info I could help more

Crank shaft sensor.

If the vehicle runs well otherwise then tell your mechanic to cleaner the throttle plate and the inside of the throttle body. He might want to remove the IAC motor and clean that area as well. Tell him to be careful with the IAC motor. This is a fairly common attempt at resolving these types of problems, you may want to find another mechanic if he did not suggest trying this.

Possible areas of concern are:

• faulty MAF (Mass Air Flo) sensor
• bad EGR (Exhaust Gas Recirculator
• bad TPS

It's most likely a combination of the 3 but the main cause would normally be the TPS (Throttle Positioning Sensor) which regulates engine idle speeds under different conditions.

Idle Contol Solenoid,at base of throttle body

Worn Spark Plugs and Dist Cap,will give you part of that

it sounds like you have fuel starvation. try cleaning out your carbourator

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