I have a toyo 91 4 runner motor 3.0 and I'd like to know what is the cause of this
Problem I took off the intake chamber to replace a hose which is suppling the cold start injector but it started staling & hesitating a lot I did intalled a new intake manifold
Gasket but I did take off the intake chamber again and I found a problem between the intake
Chamber and intake manifold gasket there was a lot of fuel in 2 holes. Please tell me what
Is causing this problem. Thanks

The cold start injector on these leak. Take it out again, leave the fuel line attached, place a rag under it, and let it sit several hours. The rag will be soaked with gas.
