Mitsubishi Repair: 94 Eclipse engine dies, clogged catalytic converter, mitsubishi eclipse

Question
I have a 1994 mitsubishi eclipse 4 cylinder EFI., my problem is it keeps dying when i come to a full stop and its shifting gears,or when i first start then put it in drive it dies, but if i step on the gas it wont, i adjusted the idle , and that didnt help. Its an automatic transmission. someone told me to get the transmission rebuilt, others told me it can be the servo down switch or torque converter, id like to know your opinion first before I do anything.
Thanks in advance

Answer
Robert,
This could be caused by a number of things.  I have seen this problem with a car that had a clogged catalytic converter.  Also, a malfunctioning fuel pump or other faulty fuel component can cause this.  Ignition and timing issues can also cause stalling problems like the one you're experiencing.  It would be a good idea to have your car's computers inspected.  Read this article for further information:

If your ECU or TCU is malfunctioning, you can get these problems.  But I wouldn't rule out an overall transmission problem.  I would have the other items inspected first before doing work on the transmission.  Transmission work should be handled by a transmission shop or the dealership.  The average local mechanic isn't as well equipped for working on transmissions.
Good luck!
