Hi everyone.
5.7L with 66RFE
I have a 2017 2500 slt with about 200k km (125k miles). I've searched the forums but haven't quite found my situation.
About a year ago, the truck started to struggle climbing hills ( my driveway is a 300' hill with turns covered in ice and snow) . I parked it for about 6 months with the intention of getting back to it.
After about 6 months, I fired the truck up and it ran fine.
After driving it the last 6 months it has slowly started to bog down. Seems to be getting worse. Odd that it sitting seemed to solve the problem for a time.
Symptoms ( I live in cold climate and mostly drive the truck in winter):
When engine is Cold:
- Starts fine, seems to back up slowly fine, I put it in drive and it will move without throttle. But (sometimes) if I give it any throttle it will bog down.
- Acceleration from stop is terrible when cold.
When engine is Hot:
- Light pressure on throttle bogs down. Continues to bog down until I hit about half way on the throttle. It drops a couple gears and it accelerates a little too well. Doesn't seem to matter which gear I'm in. If it doesn't drop a gear it won't accelerate)
- If I'm climbing a hill in any gear, it will struggle until the rpm hits around 2500 - 3000. After that it wants to go.
General:
- When it downshifts it usually skips 2 gears and feels like a race car..... whether I want it or not. I am putting in a new valve body soon.
- I cleaned the TB yesterday. Didn't seem to help. Noticed oil in the intake. I'm assuming that is from the PCV when i need to punch it to climb a hill.
- I cleaned the PCV yesterday. Seems fine.
- new air filter.
- When not in gear it seems to rev fine.
- very slight fluctuations in rpm when travelling at steady speed.
- gas mileage has **** the bed hard.
- Cam shaft tick. Planning on fixing that soon.
- NO CODES. No stuttering. No shaking. Just no power at low rpm.
At first I thought all the problems were due to the tranny. I'm going to replace the valve body and replace the tranny oil soon. But now I'm wondering if the bogging is an engine issue instead.
Any help would be appreciated.
