Toyota/Lexus UZ Engines The Random Misfire and the Fussy MAF 

Hello I'm Brandon from South Africa in Durban thank you so much for this video it's of great importance to me cheers.

I had same issue, today I came across same hose in different engine , the hose it self hard and brutal and had a split right where connect to the manifold, changed it the engine running like a dream now , I only had misfire mostly in low rpm, had it about couple of months now ,yr videos really inspiring. Thanks

Very nice demonstration!

Greetings l have 1 acting wierd like excess air coming from somewhere Recently took out injectors for testing and l was surprised to find unburnt petrol which was looking blackish in between the inlet manifold Before l removed the injectors it was smoking white petrol fumed exhaust gas And on the dipstick the level is up oil and petrol mixed together I am still to put back everything because they all seem to be working fine

Question my acis is not working can I just closed it with some zip tides and drive it like that until I fixed it properly thank you

Do you have a contact I have a 1uz sc400 and I recently changed the starter since it was bad now my car starts but stalls and sounds like it’s misfiring I changed the injectors but I do have a code for bad maf would that likely be the culprit I can send you pictures and videos if necessary this is my daily driver

I fixed my misfires on bank 2 with this fix…. But now I have misfires on bank 1 and checked pcv and hoses and can’t find anything new plugs and coils too.

I think this is the problem I have because the vehicle was standing quite a while and I have a bit of a misfire when it's idling and I think it's over fueling sometimes.it has like a lag on low revs when I step on it Do you think it could be the same problem?

I have a problem where the pipe which goes in the air box is broken so the pipe is hanging inside the box does that make any difference
