89 f250 460 cel flashing
i have an 89 ford f250 4x4 5 speed with a 460. i have a check engine light flashing on light acceleration. doesnt do it when the truck is fully warm. when i first got the truck it got horrible mileage and never got fully warm. replaced the t-stat and coolant temp sensor and the mileage improved and it warmed up faster.
anyway the cel flashes on light accel and when im cruising. i thought maybe tps but it isnt consistent. no hard codes are stored. i also cleaned the iac valve recently
any info is much appreciated.

You need to check the codes with the self-test.
Then post them back on this thread.
If you do not know how click on the link below:
Fuel Injection Technical Library » How To Run a Self-Test
OR
It it is much easier to use a code reader like the one below:
You can get on at amazon for $24.99:

OR
At O'Reilly auto parts for $31.99, cheaper with no shipping:
