Well it's on the road and running like a bag of crap

the idle is all over the place, when i set tps to a recommended setting which it has been before 0.35v Closed Thottle i can't get near WOT figure of 4.5-5.0v then when setting the warm idle it works the complete opersite when cold the car won't tickover and i've done all of 50 miles and i've had enough. i've cleaned the iscv which appears to be working.
I genuinely keep thinking of just locking away and leaving there.
The car handles well but knocks and bangs, kangaroo's, whines you name it and it's about a million miles from being a road car now which a couple of years ago was great but now i want to use the car with the family it's feels like i can't which is the enjoyment part straight out the window.
And top it all off it's done the last 25 miles to £25 of fuel, it's massively overfueling and i'm now where near anyone that can set up these.
It's booked in with James at MSD for live mapping in 5 weeks and i still need to put 750 miles on the motor which if i keep going this way will be fucked by the time i even make it there.
Totally disheartened with it if i'm honest and just want a basic car i can run in then enjoy after mapping
Question for any engine builder, tuner.......
One option is to drive it down to Blackpool 93 miles away but i wasn't sure if sitting on the motorway for that length of time is going to be idea for bedding a new motor in?
