420A 1997 Eclipse GS stalling issues

[violentconker2]

I have an 1997 Eclipse GS, I've had her for almost a year and just recently running into stalling problems. When I would turn her on and not even 30 seconds later she would die even when I come to a stop at a light sometimes.

I've replaced the EGR valve, throttle body from what the codes came up but still no change in it.

Any thoughts what it could be?

Perhaps the ISC? And make sure it is adjusted properly http://vfaq.com/mods/BISS-2G.html

IAC sensor, or ISC one of those will be the culprit! for me it was the Idle Air and I didn't even change it, I just cleaned it.

OP has a GS. The BISS is for a 4g63, not the 420a. What were the original codes OP?

^unfortunately these cars throw codes for TB related issues too easily, so people wind up replacing tps, iac, etc when that's not the problem. Try cleaning the MAP sensor. Before anything, check your battery connections. It surprises me that some 20 yr old cars still have the original dinky loose terminal connectors which pop loose over every bump and cause all kinds of problems. OP, what happens when you try to give her some gas? Does she just randomly die, or only under load? Did you check fuel/spark? I had a similar issue on an old GS; I totaled the car so it was no longer an issue.

hey guys sorry for the late response! yes so ive changed the throttle body also, and replaced the dinky terminals. ive yet to clean the MAP sensor yet. and she dies when turning, coming to stop at a light sometimes. like she will hit 200rpms then acts like she wants to catch her self and then just dies sometimes. so yeah its random. even when barely starting the car she hits 1000rpms then drops drastically to like 200 rpm again. no issue when driving just when turning on, going to a turn or a stop sometimes.
