The check engine light on my 92 f150 4.9L comes on after approx 10 min.
When I shut the truck off and restart the is off for another 10 min.
Would appreciate any input.
not sure what to look for.

Thank you in advance

Cannot realy guess. Yopu need to have it scanned for codes. Take your truck to autozone they scann for free. Just be careful when buying eletrical parts as most of them are not returnable.

Thank you for input

I checked with AutoZone and they said it could br EGR,EGR sensor or vacuum leak,I don't have a lot of money EGR and Sensor run approx $95 ea.

Not sure what to do?

Well if it were me i would check for vacum leaks and pull the EGR valve and spray it down with some carb cleaner.
