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

I'm with Red, sounds like an injector possibly. Also could be the EBPV, mine was awful until I took off the EBPV tube and cleaned it out.
|
Possibly a bad spot in the pedal assembly.

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? |
Thanks for the suggestions!
Truck has 190K miles. It happens consistently. |

So did u get it fixed? What was the problem?

Been swamped, haven't had a chance to look yet.
