I have a pick up truck. it acts like it is gasping for air/gas when you are starting it or getting her moving. She chugs and pukes and sometimes backfires. I have replaced both O2 sensors and the catalytic converter is clear. I have used carburetor cleaner, and now I was recommended this product called "Sea Foam Spray" engine cleaner and lube. did not work. Help! Beth

Hi Beth,

I know you might have done this already but I need to ask, have you replaced the spark plugs recently? If not I would start there and use AC Delco plugs.

Here is a guide that will give you an idea on how to do the job:
