HELP pls help diagnose
picked up a sc4 about 6mnths ago and she ran great up until a few weeks ago. She'll run fine in the morning but on the way home home stuck in traffic she dies out. I can start her back up, but to keep her running I have to give gas to keep her running.
any help is greatly appreciated
Thanks....

Did it throw any codes? Any smoke anywhere? Any other symptoms? If it won't hold an idle as you're stuck in traffic it might be something from below:
High engine idle speed (Poor idling)
1. A/C signal circuit (Compressor circuit)
2. ECM power source circuit
Low engine idle speed (Poor idling)
1. A/C signal circuit (Compressor circuit)
2. Fuel pump control circuit
Rough idling (Poor idling)
1. Compression
2. Fuel pump control circuit
Hunting (Poor idling)
1. ECM power source circuit
2. Fuel pump control circuit
Hesitation/Poor acceleration (Poor driveability)
1. Fuel pump control circuit
2. A/T faulty
Surging (Poor driveability) 1. Fuel pump control circuit
Soon after starting (Engine stall)
1. Engine immobiliser system
2. Fuel pump control circuit
During A/C operation (Engine stall)
1. A/C signal circuit (Compressor circuit)
2. ECM
