I have a 91 tpi it will start but will not stay running stalls if you step on the gas. It was running normal for the first few minutes then stalling I wrote on the forum and was told to changr the ignition module I replaced the entire distributor and timed it . It continued I have replaced the coil the fuel pump and filter i cannot figure the problem out this car ran great it is not trashed or modified in any way.

 

try the o2 sensor if its bad it may be leaning or over richning it. also i would change all the sensors too
not for sure could also be a bad ecu just keep that in mind if changing all the sensors doesn't work
