This is my first post/message so forgive me if I get things wrong.
I own a D Special which had an a DS21 i.e. engine and 5 speed gearbox upgrade (?) some 20 years ago. I have owned car 2 years
I recently changed a fuel injector (it was leaking) to a slightly experimental type.
When I restarted car, the idle speed was a rather furious 3000 rpm.
I have checked the obvious things like
- disconnect throttle cable
- disconnected new injector (and all the others also)
- disconnect cold start system
- checked for air leaks
- checked sensors etc but to no avail
Any one got any thoughts on what might be the problem
I was also thinking of upgrading system to a Microsquirt ECU etc.
Anyone hear if this has been done?
