Check engine light under acceleration
I have a 1989 f250 7.5L and my check engine light starts blinking under acceleration but extinguishes once I let off the gas

That means the computer senses a problem and now most likely has stored the code in Continuous Memory (CM).

Run the Key On Engine Off (KOEO) tests and Stored Code display from (CM).


Paperclip method: Fuel Injection Technical Library » How To Run a Self-Test

Or highly suggest to invest in a good code reader such as the Innova/Equus 3145.
