Smile Varying throttle on startup?

Hi All, I have just spent the last few days putting my car back to standard ready to be taken away by the insurance as a CAT C.
I had numerous mods bigger rad, ECU, etc etc.
Now I have removed everything that I can think of except the bigger fuel pump from the supercharger install but access is impossible with the rear end damage!
Now I have come to start the car and the engine is revving from 1.5k to 3.5k constantly? It does drop slightly as the car warms up to a peak of about 3k.
Any ideas?

It is due to be collected so any ideas would be appreciated

If it is being written off surely it doesn't matter?? maybe it is just down to the fuel pump chucking too much juice in

I'm not an expert mate, but your exhaust was pretty mangled, would that have an effect?

It drove fine when I collected it from Honda after the smash! It could be the fuel pump and I understand about it being written of but having taken the mods of, it should still be driveable in standard trim1

Stop being over attached to your baby.

Not your problem any more.


It's most likely going to be broken up into individual bits.

if you have the walbro 255 fuel pump in it wont make a difference, put on in my mates car a few weeks back as i fitted a new soft top, so that he can go fi in future

have you check all air breather pipes etc on the intake, fuel pressure regulator back to

Hi Phil,
Yes I think I have got all the breather pipes back on correctly, luckily I have Rebecca's to compare against, I have just spoken to Richard who thinks it may be injector related so back out to the garage!!

When I fitted a faulty MAP sensor, it produced these results
