jlpower Posted August 12, 2005 Share Posted August 12, 2005 I need some help with my 1993 SC400. I bought the car about 2 months ago. Since then I've had a to replace a few things, mainly the serpentine belt tensioner. Besides that, nothing under the hood. Every thing was fine until about 2 weeks ago when I notice it was driving a little rough. Then while on the highway, it started to run like total *BLEEP*. When I mat the gas I get no acceleration. It runs at about 300rpms at idle, and when the throttle is pressed, it is very rough throughout the rpm range. Like its only running on 6 of the 8 cylinders. The exhaust smells very very rich to me. I was told that the timing belt needed to be changed, but that was done 40k miles ago, and after inspection, it looks almost brand new. Any ideas? -Jon P Quote Link to comment Share on other sites More sharing options...

jlpower Posted August 14, 2005 Author Share Posted August 14, 2005 Got a call from the dealer (Toyota). Turns out the timing belt tensioner caused the belt to jump some teeth. Both the belt and the tensioner need to be replaced. Quote Link to comment Share on other sites More sharing options...
