Mile_High_Flyer Posted March 18, 2019 Share Posted March 18, 2019 She suddenly started idling very slow, and surging, When I got out and went around the back, the exhausts were emitting black smoke. When I got home, I left it overnight, and it seemed to be okay this morning, except possibly idling slightly high. This afternoon she was okay for a while, then started back with the surging and slow idle, At the lowest point, about 200 RPM the CHECK ENG message flashed on for a split second, Other than that, there are no warnings, and one of my OBDII sensors showed no codes. Haven't checked my other sensor yet, I'll do that tomorrow. At one stage I gave it heaps, and it appeared to be quite good for a while. When I got home, there was no smoke, but there was quite a smell. I've only just now thought , I wonder if the cats might smell through working hard because of how rich it was running, Could that be the case? Any thoughts, anyone? Thank you.

Mile_High_Flyer Posted March 22, 2019 Author Share Posted March 22, 2019 Update. She appears to be running fine, and according to the fuel consumption figures etc, all is good, but she has to be still running a bit rich as the exhaust pipes are black, and there is still some smell, but I still don't have any codes from either of my OBDII checkers. I am going to try disconnecting the battery for a while in the hope that it might reset the computer, but I'm not gonna hold my breath!! Other than that, I don't know. Might have to bite the bullet and go and see Toyota. Quote Link to comment Share on other sites More sharing options...
Mile_High_Flyer Posted March 25, 2019 Author Share Posted March 25, 2019 Another update. I disconnected the battery for about an hour and a half to make sure there was absolutely no residual voltage, or anything else! Then reconnected and went for a 40km ride. (About 25 miles). Fuel consumption figures looked good, and when I got home, no smell, and exhaust pipes were a lot cleaner. So I cleaned them, then went for a 20km ride. Pipes as clean as a whistle. That was yesterday. Today I went to work this morning, and back this evening, About 40 km each way 6.4L/100km, 36.75 mpg US. 44.14 mpg Imperial. Mainly on motorways (Freeways) mainly about 80km/h, 50mph. and again pipes absolutely clean. I'm very happy with that. I have no idea what caused the problem, because the same tank of fuel was used all the time. Cheers. Quote Link to comment Share on other sites More sharing options...
