Konking out at lights and occasionally difficult to start
Discussion
Found that when I am travelling in a built up area and I stop at the lights it sometimes idles badly then dies. Girlfriend (who know wants to sell my pride and joy) fired it up was manouvering and then it konked out in the middle of the road) and had loads of diffcultyt restarting, which she eventually did.
Other points:
Just had air intake rebuilt under warranty;
starter motor is working;
fuel pump is wiring before start;
Is it a case of new plugs and magnecor leads(have factory standard ones, please help so I am not forced to get eurobox!!!!!!!!!!!!!11111

Cleaned the stepper recently? See www.car1.clara.co.uk/tvr/stepper.htm
Could be any number of things exacerbating the problem, old leads etc may well not help, neither will poor quality dizzy caps and rotors, the coolant temp sensor could be faulty...about £5-10 to replace, Intermotor part number is 55128 - this replaces the Lucas SNB802 part.

You might have an air leak from the work you've had done if it's only happened scince you got the car back?It also could be the stepper motor needs a clean,theres loads in the archives about how to do this.I certainly wouldn't start spending mone on new leads etc just yet(missfires are more common with bad leads).For what its worth,i've always found std leads to work just fine,and last a long time,even on the modded griff

Sounds like my problem on my Tamora (2004 model) when I was on a long run. If I pulled up or went very slow walking pace in traffic she'd cut out. This went on for around 30 mins, as I arrived at my destination she cut out totally. I had a flight to catch and did'nt get chance to sart her for an hour at which she started first time. However half a mile down the road she cut out again. Faulty alternator diagnosed by the AA and new fitted under warranty and all's well. :-)
Have just tried to clean stepper motor as am due to drive Newcastle on Saturday. As it was getting a bit too dark decided against taking the job on.
Thought I would fire it up anyway to see how it was running - with the bonnet open could here a sucking sound coming from the area around the stepper motor - so reckon this probably explains the problem.
In the dark couldnt see much, think I could feel the air leak. Questions are as follows:
1) Could the stepper motor have been overtightened and cracked the plenum or the threading in the plenum causing the leak?
2) Is this less likely as when I got the car back from the garage the problem wasnt occuring, meaning that it has just loosened off?
3) How tight should it be and is it worth running some kind of sealant around the stepper?
PS I dont profess to know anything about cars, which is why I work in an office....although I think I could start to enjoy getting my hands dirty (subject to not killing the car)

Had a look at this morning and tried to tighten it, with no effort at all the thread sheared, now I willing to admit my errors but I am pretty sure this had already happened hence the leak.....
Whats involved in getting this fixed?
Will the plenum have to come off or can it be fixed it situe by removing the backplate on the plenum?
Also how much will a new stepper be, I have been quoted £97?

Yep unfortuantly they are around the £80 - £100 mark.
Can be changed very easily. See the chassis33 comment earlier with a link to cleaning the stepper, basically you can use the same instructions to change the stepper.
Plenum stays wher it is so it really is just unplug, Unscrew stepper ( clean where it went into and check the thread is ok in there) PFtape the new ones thread and screw in.I realy do hand tight then just nip it p very carefully with a large spanner.Plug back in.
