Hi all, I need some advice. I’m not familiar with these ford trucks. It’s an 88 F250 5 speed 460 single cab long bed 4x4. I keep getting a check engine light and the truck cuts out trying to drive it. Seems it only does it once warmed up. Trouble codes I’m getting. 82 84 key on engine off then 22 and 33 continuous memory then 12 with engine running. I’ve changed the pickup in the distributor and the box on the outside of it (can’t remember what it’s called) map sensor throttle position sensor the sensor on the egr valve and the computer bought remanned from the parts store. I haven’t had this truck more than 6 months but all this started recently. There’s at least some of the vacuum stuff been taken off, I assume it’s part of the emissions system but the truck ran great the whole time I’ve had it until now. I have an O2 sensor and egr valve ordered. There’s no catalytic converters. I also just replaced the high pressure fuel pump and fuel pressure regulator in the last month. I need some help here. I’m an ok mechanic but this electrical problem has me stumped and I’m tired of throwing money at it. Can someone give me some suggestions as to where to look please?

Welcome to the site..

When it’s drivability falls off,,, what’s the idle like?
Smooth/stable?

when the check engine light comes on it idles about 1000 rpm when it goes out it’s normal maybe a little low..

also thank you for the quick reply
