ok well the codes i got were
E27
E31
E52
E71
F40
.7.0?
and then the car just started right up. no hassle at all. i have no idea why? i just turned the key and it started. i dont understand. someone enlighten me
E027 - EGR
E031 - shorted MAP sensor
E052 - PCM memory reset
E071 - Intermittent MAP
these are not in my books:
F40
.7.0?
================
if the car started, I assume all the codes were "history" as compared to "current."
You may be in luck .. the MAP sensor is usually located atop of the intake manifold, passenger side towards the firewall .. the connector tends to break down due to the age and heat and E031 & E071 point to that ... check that. Sensor may be bad, but that is less common.
the EGR error may be connected to the MAP error but if you correct the MAP issue and the EGR code returns, you are looking at a EGR.
when you deal with the MAP and/or connector, clear the CODES and see what returns if any.

Exhaust gas recirculation (EGR) is a NOx emissions reduction technique used in engines and works by recirculating a portion of an exhaust back to the engine.
The video is the idle air control, IAC .. it does that.

oh okay, well, do you have any idea why it wouild be stalling after being put in gear? and sometimes not even then, do you think the throttle body should be cleaned out or something? it looked pretty dirty when i looked inside, sludge and stuff was in it

a carbon filled throttle body will make an engine idle rough, stall, etc .. it never hurts to clean it and some cars, need it often ..
regardless of the throttle body, the diagnostic computers have spoke .. they rarely if ever, make a mistake .
