Thanks in advance for all suggestions and advice. My engine is running in safe mode, no error messages.
The following is a list of work I've done:

• new distributer when I had PIP error 2 years ago
• swapped ignition module
• swapped coil
• new rebuilt mass air flow sensor
• new plugs w/ tune up 2 weeks ago
• new wires, cap, rotor w/ tune up 2 weeks ago
• fuel filter
• fixed multiple vacumn leaks

When the engine is cold runs ok but when warm loads up and stalls. I unplugged the mass air flow sensor and the engine runs but very sluggish. I think the only thing left is the engine control module, but I'm running out of money. Any ideas or suggestions?

 

FYI ....It was the O2 sensor

 

I hope it was a Black one that swapped in.
A Gray one will not give as much power and poorer MPG.
