rev's dropping
Hi
when im driving my 2000 impreza hen i come to a stop or to a juction
the revs drop and some times cuts out...
i have just had it re-mapped and was fine before it was re-mapped
i have cleand the idle valve and checked all the pipes
the only thing is that i ahve a blitz dump valve fitted could this be the problem?
thanks

How is the idle stability generally, btw? Once it settles down does it stick at roughly the same engine speed or does it hunt up and down?

it was mapped by clive atthowes and its mapped with a
its a 2000 uk turbo
apexi power fc with controller
hybird gt 2 fmic
blitz dump vlave
hrc fuel pump
hks air filter
all these parts were fitted when he mapped the car
he told me he had no problems while mapping it,it had a new air flow meter a few months ago
it idles fine its only when you stop....

If the CTS is faulty, you'll see a suspect reading on the commander.
TPS should read approx 0.5V on a closed throttle and 4.3V when fully opened - Theses can be checked on the Hand Commander under the ETC-> Sensor/Switches screen.
Possibly a MAF or ISCV fault.
What Airflow reading do you get with the Ignition on, engine not running?
What airflow at warm idle
Also worth asking whoever mapped the car, what the Fuel Cut (F/C1) and Target Idle Speeds are set to.
