yes, that scenario could be the culprit I have since put everything back and the vehicle is in running condition, after the bank 2 head job. test drove it on highway, grocery shopping, different errands etc, I am though still dealing with 2 fault codes that won't away P0038 P0058, which are...

Also at least to my knowledge , my model 05 4runner 2uz-fe doesnt have a conventional fuel filter. there is a screen on the fuel pump it self. wouldnt hurt to retrofit a fuel filter

I think low quality fuel and old fuel could ba a cause to clog up injector. leaky injector could cause misfire and leaked fuel keeps burning Then the port gets too hot....etc just a thought, not exactly sure what had happened

I can definitely see how a leaky injector be the culprit. my Cylinder #4 bent valve solution was = head taken out and brought to machine shop to have bent valve replaced. bought an used intake manifold (mine also has a hole on intake port #4), the 4runner is sort of running now after 5 months...

Didn’t find the cause. I bought the runner knowing it had problems with very rough idling and misfires at all cylinder I assume the timing was jumped and or the timing belt Broke off at some point.

so I double checked again by rotating the engine and while feeding mosquitoes, one of the valves is indeed stuck open stuck a long thin screw driver also to verified, while the same runner neighboring valve was closed shut. next questions: 1) do I remove the engine so I can take the head off...

so I got back to the project, got bitten alive today by mosquitoes (Freaking Texas September weather and rain) Observation: subject problems port has a valve stuck open, won't move and I rotate the engine. does it look like it is bent?

thanks for the reply I was out traveling for the long weekend just got back into project 4runner i'm taking the valve cover apart. I did notice the subject port's 2 intake valve seen to be "dropped" they are just sitting there, I observed suspect valve stems wear marks they seem off I will...

other possibilities that I can think off clogged exhaust, backed fire? Blocked EGR? could it be melted while the manifold was taken off? poor workman ship with poor environment , e.g cigarrette ashes while manifold was on the floor during serviced? still trying to wrap my ahead around the lack...

Thanks for the reply, I think the power goes to the Injector are low, and not high enough to generate plastic melting heat. I could be wrong. I took out the all injectors about 10 days ago, this was before I took out the manifold, and before I saw the melted part. The injectors seems to be...

fellow 4runner lovers, I'm scratching my head on this. Recently acquired an 05 4.7 V8, 2uz-fe, I believe this has the VVTI. Rough Idle, with Misfiring codes (All 8 Cylinders) spend a couple weeks, on and off to troubleshoot. I have previously sprayed Carb cleaner before at cold start during...
