1KZ-TE rough idling
Posted: Sat Apr 29, 2017 2:26 am
hi guys,
my engine is keeping me busy....
it falls into a very rough idling from time to time and I can´t tell why. no matter if cold or hot, could be anytime.
here is a clip https://www.youtube.com/watch?v=UgXXqxiCtc0
I had fitted a transparent hose because I have air in the fuel filter again. damn primer pump again. had to replace it in every toyo i had so far.
however, it will only suck air when the pump is pressed down and even then when you see air bubbles in the hose, the engine would not sputter and nothing.
so I would not dare to hope it has something to do with air.
i had my injectors changed 30 k kms ago.
i adjusted the pump to accomodate the intercooler with 1/3 turn in.
I very much believe the rough idling started only after fitting the IC but I really can´t recall. it got more obvious then because the IC was rattling against the hood until I adjusted the space.
i just returned from a trip to the Tunisian Sahara, did 4000 km´s and have to say it did great in the dunes. nice torque and the side exhaust comes in nicely. was working on my own dump pipe before the trip but didn´t dare installing it without being sure about the setup. the vibration of the engine idling let a welding seam break on my down pipe at the turbo flange when I was leaving the dunes and had it welded in the next village. but it´s again starting to crack and I am sure it´s about the vibration.
any recommendations?
thanks
peter
