low rpm stalling
So I cleaned my EGR and replaced my IAC in an effort to fix my stalling problem when stop. It agrivated it and now below 1500rpm, she loves to stall out. Should I remove my EGR and see if that fixes it? My old IAC is pooched, the spring is bad. I cleaned my t-body as well. What do gods of third gen?

Re: low rpm stalling
This is going to sound strange but it could be your torque converter. If you have a lockup TC on your car it should unlock when you slow down. If it doesn't, your car will stall when you come to a stop. Yeah, I know it sounds weird but I experienced it first hand. It took an 60+ year old third gen fan to figure it out. Replaced the TC and the problem went away. To clarify, this only occurs if you are slowing down from cruising speed. It really depends on your TC. If your car stalls when you start it or when leaving the driveway, this isn't the problem.

Re: low rpm stalling
its not the TC as it stalls in any gear, park, nuetral, drive, and gear at all. maybe my IAC passage is blocked up? or my EGR **** hte bed? im thinkin its a fuel or air problem cause to start it i need the t-body all the way open.

Re: low rpm stalling
after reading like 15 threads on this problem, i think i have it narrowed down to CTS and fuel filter. considering i have to give it gas to keep it running and have to pump the gas while starting to get it to start, im leanin twards a dieing CTS

Re: low rpm stalling
what 's a CTS? i am tring to figure it out wha's going on with my 90 RS.
when i'm driving it's fine , but when i step on the brake at a light or a stop sign, the rpm goes up and down ,and if i don't give some gas, it would just stalls, is that what was hapening to yours?

Re: low rpm stalling
stalling when you're stopped could from a bad VSS (vehicle speed sensor) this tells the car when it's moving and can mess up idle speed.
