[urq] More of the car that wouldn't start

My first thought would be to pressurize the intake to make sure you have no
vacuum leaks.  If the car is sealed - then next check your duty cycle.  You
may have had a leak before that is now gone- hence throwing your DC way off.
I once fixed a "minor" leak that threw my DC off so much the car would die
immediately once off the gas - wouldn't even idle.  I had to blindly give
the 3mm a turn  - luckily I went in the right direction and the car was able
to idle while I walked from the driver seat to the front so I could properly
adjust it...
