    It looks like there is a drive on the end of the stepper motor so I'm wondering if whatever that the stepper motor moves may be stuck. Does the plunger just move in and out or does it rotate?

    Thanks for the offer Garry. That's too kind. It will be a few weeks at least before I'm able to travel with the car unfortunately. I'm balls deep in few jobs on it at the moment, and once those are done I need some welding for the MOT.

    Hi Tony, yes the motor can be adjusted manually, thanks for the tip. Maybe I can warm it up, then adjust the stepper motor manually, then with it unplugged adjust the idle screw. Hopefully it works better now I have replaced the o-ring. I'm also going to a local community repair group on Saturday to have my MAF PCB repaired, how great is that! P.S. do you know what it is that the stepper motor is moving?

    the original auto boxes were pretty good. that is what i fitted along with the correct ecu after my second gen box got trashed after a heavy launch. never had an issue with the auto box since I must have 100's of launches on the auto box, pre and post engine rebuild, with high boost, high torque at low rpm. the above launches are also a good way to trash conrod and crank bearings. especially if you use crap engine oil. never go cheap on engine oil or ATF.

    Thanks guys, thats bad news. I followed the instructions that were included with the stepper motor. I will look into getting a cable and evoscan. It never ends...

    do you have a link to the thread you did about full idle setup using evoscan to lock the stepper motor and set the idle with the BIST (Base Idle Set ???) screw. post 10 gives a good description of what to do to set the idle correctly if you have adjusted the BIST screw randomly.

    Davezj replied to a thread Head Gasket Replacement in Engine
    i have been running 320hp plus for the last 10 years and it easily handles this. i had 320hp on 1.1-1.2bar boost pressure. the reason i had 3 engines with head gasket fails is because i run the turbos with with no wastegate pipes connected so they boost as hard and as fast as they can. full boost 1.6bar at 2500-3000rpm. massive torque very low down in the rev range is lots of fun to play with, but it will lift the heads if you have standard head bolts. my point is i have not dynoed my...

    Davezj replied to a thread Head Gasket Replacement in Engine
    I have done head gesket replacements on the 6A13tt engines. engine out is a much easier way to do it. unfortunately in both of the engines i have done the head gaskets on, once the engine was out and the bearings were checked it was found they needed replacement. so what was originally a head gesket job it turned into a full engine rebuild. you can take the rear head off the engine while it is in the car, but would not both it is more hassle than it is worth. just drop the engine and...

    yes its possible. I had an issue the same as OP that that happened once, but the car has been off the road for the last month. I also seem to have an issue where the revs are not raising as I would expect on cold mornings, which made think it was a MAF issue. I also had a strange experience when changing the idle speed stepper motor, the instructions said to turn the speed adjuster screw all the way in and hold the rpms at 2000 until the engine was warm. then back it out the 650rpm. ...

    Well I've run the test as instructed. The resistance value at 20c was good and it changed as i heated it, although i'm not to confident on how accurate my probe thermometer is measuring air temp. It seemed slow to react. So the upper reading wasn't bang on. So maybe my diode is ok. Bit strange, i might take it to be looked at anyway.

    Thanks for the offer Garry much appreciated. I spoke to Mike at viamoto recently and he mentioned the diode was faulty on his brothers legnum. I've done a diode test with a multimeter and I think the diode itself maybe faulty. The test guide instructed to remove one side of the diode for the circuit before performing the test which I was unable to do however, so I am not 100% sure if that is the issue. There are some PCB repair shops near me so I will try and get it looked at once they open...

    Hi Tony, I had a potential MAF fault recently and came across this thread I've had a a look at the circuit board as you suggested. I'm not really sure what to look for when you say crystalised solder. I've taken some pictures there does seem to be some brown stuff as you can see. Notably a couple of the tabs on the cover were broken so it looks as if someone may have been in before. I've taken some pictures maybe you can suggest if these solders need redoing. Thanks Steve.

    Hi there spoke to you before with few issues with my 1996 legnum.well at the moment it running fine touch wood just want to no any contacts that could. Remap mine and hopefully have a newer ecu as mine is 7201, have spoke to Jason about remapping and other ecu to fit but for some reason won't get back to me hope you can help

    Many thanks
