i just picked up this 97 f250 hd 3 days ago-today the check engine light came on & the truck started shifting real roughhalf the sensors under the hood have no power obiously a short somewhere...any thought on where to start looking...except for the c.e. light & the nasty shift everyhting else seems normal

 

The place to start is to retrieve the codes that the CE light triggers and stores with a scanner; everything else is speculation if it's not an obvious problem.

 

max i took your advice. i brought it to the dealer today-they told me it was giving them false error codes-but they think it is the tps...that doesn't make sense why would the other sensors lose power just because the throttle position sensor died...no too sure if this makes a difference but it's been raining for the last day & when i drove to the dealer to drop the truck off the light never came on & the truck ran fine
