No power, no codes

Listen to the little bird...

 

It's easy to test if the clutch is slipping. In a particular gear the speed and rpm should always be proportional whether you let off the gas or floor it. For example, in 5th gear, maybe
2000rpm ~ 40mph,
2500rpm ~ 50mph,
3000rpm ~ 60mph

If you don't have a tachometer use the live data from an OBD reader to see rpm.

 

Did a quick test regarding the clutch that someone suggested. From a standstill i put it in 4th gear and slowly let out the clutch and it didn't kill the engine. I was hoping this wouldn't be the case. Not something I'm setup to do on my own either. Will have to start calling and getting quotes. I know i'm on borrowed time with 202k on the same clutch but just after having a parked SUV totaled by a drunk driving, having another vehicle with a major issue isn't something i was wanting to deal with.

 

Test for slipping clutch. Get truck moving about 15-20 mph, shift into top gear, plant the throttle. If your RPM jumps up it’ll be pretty obvious the clutch is slipping.

If not clutch, I would think possibly catalytic converter (if part of the media is broken up it could cause one Hell of an exhaust restriction) or possibly primary O2 sensor (doesn’t have to throw your A/F ratio off that far to cause a lower loss.)

 

Sorry to hear, hopefully you can find someone local with a decent labor rate to do the job.

 

Or, back the truck up till it’s touching a large tree. See if it stalls or you smell it. I don’t believe your clutch is bad. You have been driving a standard long enough to be able to determine that. If you have a scanner, report back w/ LTFT at a steady cruise.

 

Does the truck run well cold and act up when it gets hot?

 

He just posted yesterday he confirmed it was the clutch.

 

nice to know the internet diagnostic skills are somewhat intact............

 

Well, finally got around to taking the truck in. It was the clutch. It's incredible how different it feels. Much more responsive when letting off and acceleration is much better. One thing though. I noticed when got on the road afterward i have a slight "tight" vibration from 30-50mph. I'm wondering if they got the driveshaft out of balance. Any thoughts on that? I'm going to get underneath it in the morning and see if a driveshaft weight is missing or a loose u-joint. It's never had the vibration before.
