Got a 93 oldsmobile 88 two months ago, replaced batt, alt, starter, plugs, wires, and fuel filter.

Now im having an issue that when i stop at a light or stop sign the car stalls out and shuts off i have to put it in park and start it back at. I was told to change/clean the egr valve and the ports.

Where are the ports located on the 93 oldsmobile 88 with a 3800 egine?

I had a similar problem with my 94 Park Avenue. It was the TPS sensor.

check for vac leaks and clean the iac and seat in the throttle body

im far from a mechanic please tell wat is a TPS and a IAC

THrottle position sensor(located on opposite side of tb from where your gas pedal linkage connects and IAC Idle air control (valve) is a to the left of the MAF and above the TPS mounted on the top of the tb
