    Creaky steering rack

    I had a really creaky suspension. Didn’t hear it when cold but after everything was warm would develop. Spherical bearings on the drop links were the culprit. 5 minutes to take them off and check.

    Throttle Position Sensor Adjustment

    So I’ve just put the TPS on backwards and it’s behaving as expected, revs up nicely and holds without misfiring. its definitely the wrong way around as there is a slight boss for a metal spacer to house on which is now on the wrong side and it doesn’t locate properly, just enough for me to test.

    A few pictures to help support. The TPS is on the LHS as you look at the throttle bodies and this hasn’t changed. This car hasn’t run since last summer, the battery was dead when I came to fire it up. Any possibility the ECU cleared and it’s defaulted back to out the box and the config is to have it on the other side of the throttle bodies? I’m using easimap 5.5 so cant see how to get to the second screen you’ve shown Jim.

    Jenvey TB’s not sure about the TPS, will check it tonight at home.

    The voltage is moving the same way as the TPS site. As I rotate the TPS, both site and voltage decrease.D

    Yes it has been off, but the bore is blind so can only be fitted one way. It certainly feels like its something as obvious as that doesn't it!

    Throttle Position Sensor Adjustment

    So......Cable purchased, laptop borrowed off Russ (for the small fee of beer and ice cream) and all plugged in.Immediately realised something just isn't quite right. So I can match the TPS position to 1.0 on the screen, but when I apply throttle the position goes backwards and jumps to 15.1. If I move the position of the TPS so it reads higher (4.0) and do the same, the application of throttle sends the value lower. It feels like I'm doing something wrong, so I'll put a few bits of info down, some of it may seem obvious but always worth checking the easy stuff first! - What I'm reading as TPS location is the green box on the right labelled "throttle position map sight" - I've checked the TPS is on the right orientation, it drives off a flat so can only go on one way - The connector and cables have not changed at both ECU and TPS, the TPS connector can only be connected one way - I've tried with the throttle cable connected on the pedal and without on the butterfly - This was all done with the ignition on but engine off, I assume this makes no difference but worth mentioning. Tomorrow night I'll fire it up to ensure 1.0 runs as expected. Any suggestions on the next steps to look at?

    Then we are talking about a different thing! Phew! I was a little uncertain when you mentioned turn of the screwdriver. so just for clarity, can I read the voltage through the software on the laptop or do I have to go off the middle cable?

    I changed the throttle cable when I put the engine back in so it’s game over isn’t it? I need a remap.

    Ok, well thanks for the information so far everyone, so glad I decided to post. PLAN cable should be here Monday, borrow Russ’s antique and find out my two voltages for closed and open from the software and rotate my TPS to get the same (or lower) as a starter for ten. After that, adjust the idle screw so it sits right and in theory I shouldn’t be too far from where it needs to be. Hopefully this will put me in a position where it’s driveable and then remap if it’s not spot on. might be a stupid question, I’m very inexperienced with electrics, how do I get access to the central cable where my 5v supply is? There’s no solid wire showing, it’s all protected in shrouding. Or is this something I can read live from the ECU?

    That makes sense, I can get it running fine on tick over and revving up is ok, its light throttle that it doesn't like and starts missing. Russ H owes me a few favours for my professional welding services so I'm sure he wouldn't mind me borrowing his laptop. I'll probably have to provide my own coal though!

    I think not, I replaced the throttle cable/clamping mechanism as well so thats another factor for variation. Cable and reset is probably the easiest.

    You finally come in useful for something!

    Yeh I think that was the one that I was reading, I'll get a cable sorted and check it out. Fingers crossed I get lucky......

    Reading some of your previous comments on this issue has really put a downer to my evening!!
