    Hi Guys

    OK cleaned maf sensor & map filter

    maf not really dirty but drowned it anyway

    as for map filter , I think I found the right one, as well as being a filter it's a one way valve as well

    so gave it a shot of cleaner thru it had a fair amount of crud in it

    made slight improvement, so have ordered new filter ( $55 ) toyota know how to charge for little plastic bits that are only 25 mm x 25 mm.

    toyota don't call it a map filter , it's a gas filter, so should get it tomorrow & see if makes anymore improvement.

    as for techstream cable got one that doesn't work for me, so a bit apprehensive about getting another one, got refund and was able to keep it's a 32bit (was supposed to be 64 bit).

    I'll get one eventually

    How many km's since your injectors were replaced if ever? The general consensus for non DLC injectors is to change them at 120,000km. I had my injectors done on my 150 slightly earlier than that and the engine is definitely quieter. Quieter than it was when new in fact.

    What was the injector feedback volume after the replacement?

    Well, it's not the MAF sensor for me; I clean it regularly when I replace the air filter, and I just did it again. Cold knock is still there. Also replaced the oil - the sump screen (which I check each time) is also clean.

    I'm a little worried based on what I read on this page of Bailey's website: "The Common Rail injectors fitted to 1KD engines are fairly problematic and can cause significant engine damage if left unattended. Most common failure mode is known as ‘cold knock’ which essentially sounds like there is a major fault with a bottom end bearing – only whilst cold.

    Fault is caused by the spindle in the centre of the injector seizing / sticking when cold, which causes an excess of fuel to be inputted into the cylinder."

    According to them, if the values are beyond +/-2.5mm3 / stroke cold or hot, that could be the problem. I'll get them checked, but if if my already-replaced Denso injectors, which only have about 70,000km on them (the car has 260,000 km on it) are out already, I won't be pleased.
