Help! After cleaning throttle body Trac light turned on.
Few days ago I cleaned the throttle body and it was full of carbon. I sprayed alot of throttle body cleaner inside the throttle and it got flooded. First it was hard to start car, now it starts but it idles rough and Traction Control light turned on. I checked all the vacuum lines non are unplugged. One straight breather hose right under the throttle body has a crack but it was there before I cleaned the throttle body. I already ordered the hose but it's gonna take few days to arrive. What should I do now to make it run smooth again. Whenever I start the car it throws alot of black carbon on the muffler. I don't want to drive the car because I saw timing belt has never been changed and it has cracks.

Hello Everyone. I fixed the traction light problem. The harness of the traction wasn't sitting properly but the car still idles rough after cleaning throttle body. Any suggestions? I am waiting on engine breather hose otherwise I am planning to remove the hole throttle body and clean it inside out and also replace all the spark plugs and wires.

Are you sure your 64 Toyota has all that kinda stuf?????? If you remove the hand crank it will run better.

Where did I mention 64?

Well I posted the question in the thread of 1st and 2nd generation of LS400. So it should be standard on both generations. The one I got is 91 by the way.

Nope.. changes made in designs, performance and diagnostic capabilities between those generations. Can't treat them all the same. So it helps to provide as much information as you can when you're looking for free assistance.
So, how is it running now? How many miles on it? How long have you had it? Any service records? |
Huge difference in what year it is. It determines if you have a CAN system or not. It tells us if you can or can not clean the MAF or Air meter. It tells us if the engine is VVT or not. How many speeds the transmission is. And now that we know the year we can tell you if the timing belt breaks its all okay and will not ruin the engine so all your out is a tow.
If you tried to clean the Mass air flow sensor you then ruined it. If the exhaust is black its way over fueling it. So we really need to know how it ran before you "worked" on it. If there is a hose leaking that can fool it into wanting more fuel so? And what is meant by a lot of carbon black on the muffler? You mean exhaust? I don't understand??? |

I bet the color of the car is also necessary for troubleshooting the engine problem.
And if you want an answer to your smart ass comment, the answer is yes. The color does matter. For instance, if you were to tell us you have a Cobalt Blue Metallic LS400 we would at least know it's a 90-92 which is better than saying nothing at all. These cars are vastly different across a 10 year span. |

This snarky remark says nothing to us except just how much you have to learn about the LS400...

Well I only sprayed MAF and let it sit for an hour. Yes by muffler I meant exhaust. On the day when I was cleaning throttle body I also replaced the coolant temperature sensor. Because It's horrible on MPG. It's doing 11 MPG. But I haven't driven it Since I cleaned the throttle and replaced the coolant temperature sensor.
