Bad miss
I have a 2004 2wd with the 3RW petrol engine. Have a bad miss it’s ok at idle not good as soon as I increase the revs. It is also pulsing through the air cleaner. Have checked vacuum hoses and replace plugs, plug leads and coil packs. Not sure what to do next

Re: Bad miss
Pulsing through the air cleaner almost sounds like a timing issue?

Re: Bad miss
Did the problem appear after you worked on the vehicle or did it just start by itself?

Re: Bad miss
Or it could be an inlet valve.

Re: Bad miss
I think he means a 3RZ motor.
When your road comes to an end ...... you need a HILUX!.
Life is like a jar of Jalapeño peppers ... what you do today, might burn your ass tomorrow.
Don't take life too seriously ..... no-one gets out alive.
It's not about waiting for storms to pass. It's about learning to dance in the rain.
And be yourself ..... everyone else is taken!

Re: Bad miss
If the compression test was genuinely good, then the chances of a valve problem are slim. Generally these are hardy motors that can take some abuse and don't give many problems.
Without the blow-back and considering what you have already replaced (including the compression test), I would perhaps be thinking along the lines of a dirty / partially blocked injector.
The fact that you are getting some bl;ow-back through the intake is puzzling and as mentioned could be a timing issue, but it would have to be badly out of spec. Then why would the timing go out of it's own. I'm not convinced even though it is a possibility.

Re: Bad miss
Check the idle control valve on the throttle body. It become stuck and needs a good cleaning.
