7.3L light stumble, any ideas?
2000 F250 PSD 6sp. During warm up, I get a light stumble during even throttle driving. Doesn't happen when cold or completely up to temp. Accelerates and decelerates fine throughout cold thru fully warm. Any thoughts? I have lived with this for years but if it is an easy fix, I'll tackle it. Thanks! Randy

Put a scan tool on it but most likely a cam position sensor. 10mm wrench, on front of motor.
Buy the Ford part about $47 bucks and better then cheap parts store ones.
You do want to change it they will fail and leave u on the side of the road, I carry a spare with me.

Cam sensors usually cut out then die completely, check the valve cover harnesses to the injectors, measure resistance of each injector at the v cover connector, they use a common wire at the center of the connector and 4 signal wires, the smaller 2 on each side of center. If one is off pull the valve cover and ohm the harness

Code reader will tell you pretty quick.
I have lost 2 cam sensors, one failed the other stumbled for years (Factory one).
Just saying.
BTW
How many miles? Red, does that happen a lot? Sounds like you have dealt with it before?
