Hello,
I have a 95 F-150. For the last month or so for the first 30 minutes of driving the truck pings and sputters and has a total loss of power when I give more then 1/4 throttle. When the outside air temp is higher then 70 degrees the truck runs fine from the start. I have tried posting this problem numerous times using different descriptions of the problems. But have not had much feed back. If you have any ideas of what I might check or of had a similar problem please let me know. Thanks for taking the time to read this.

 

Try replacing the air charge temp. sensor. It tells the computor how warm the incoming air is.

 

It sounds like a fuel delivery problem, i would start by checking for codes. Second you would want to hook it up to a scantool to read live data while the truck is running. Because your truck is OBD1 it really only looks for opens and shorts in the sensor circuits. If a sensor is just reading out of range the computer won't catch it, it will just adjust the fuel and ignition accordingly which could cause the problems your having.
