OVER FUELLING ON COLD START
Discussion
Hi all.
I realise this subject has been dealt with in the past and apologies for posting about it again!
On starting from stone cold, my car appears to "miss" for thirty seconds or more and will not rev cleanly. After this initial period the car is absolutely fine and the symptoms only reoccur after an overnight wait.
As stated in a previous post, all of the ignition components are new, I have just fitted a new, genuine stepper and an FAE coolant temp sensor. Don't ever fit one of the "Lucas" CTS parts as they are rubbish!
I am at a bit of a loss as to the next step. Go back to an old Weber or Su and I'd be fine but even an ancient injection system like the Lucas one has me baffled.
Is there a fuel temp ECU connected on these cars? the Steve Heath book suggests they are unused on the TVR.
Any thoughts would be appreciated.
Regards Chris.

Hi and thanks for the replies.
I tried mine again today and no change. The smell of fuel is quite strong and a little worrying, but as before, after about a minute all was fine.
Is the fuel temp sensor connected/fitted on our cars? It seems strange that after all these years so many of us suffer from the same problem. Surely the over fuelling on a cold start must be detrimental to the engine?
I only got my car, a 1997 400, last year and admittedly have only done less than 2000 miles in it. Most of the time it has been in the garage having work done on it! The strange thing is I don't recall any issues like this last year.
