I just had the same issue along with oil pressure going to zero. Reduced power and a few other warnings, stability and service. I replaced my throttle body and it ran fine. A few days later it still has a bad drag to it. When letting off the gas it feels like I am pulling a heavy load. Oil pressure still at zero but I have a good oil level and the engine is running great besides the drag.
Still researching. If you find out anything please post.
Dmj06 I am also having the exact same issues that you are having have you resolved any of these issues as this just happen to me a week ago and again yesterday Wednesday December 4th
GuruKVYZB, I've had a few other issues come up. I believe after replacing the ECT sensor (easy change out) there are no more issues with that particular problem. Now i am struggling with oil pressure issue. I switched out the oil sending unit along with the screen underneath it. (I took the entire intake off to change it). More time but was a lot easier and can see what i was doing and not guessing. Plus large hands squezzing back there is hard. I am now replacing the o ring on the oil intake tube that seems to be the issue from what I read. Good luck! If this comes to be an issue again I will update.
