ECU Reset - It's a miracle!!!
I had been experiencing sluggish performance in my August 2002 manufactured 156 JTS 2.0 litre for several weeks and was recieiving an ABS/VDC warning AND an MSCF error on the display.
I suspected the spark plugs were not quite right as acceleration was poor and idle sounded like someone with emphysema.
Anyways, replaced the plugs, disconnected all the sensors in the engine bay and cleaned connections, disconnected hoses and cleaned any deposits found, gave everything the once over and started the car. Idle much better and a bit more torque and power at lower revs.
I had a spare 2 hours so performed the ECU and throttle body reset procedure as seen on this thread and am now struggling to get the smile off my face.
My JTS is a 4 cylinder manual, factory lowered, Koni schocks, stage 1 ecu remap, K&N cone and GTA mags.
Since performing the reset the engine note is throatier, acceleration is smooth and powerful across all gears (previously 2nd and 4th were sluggish) and overall the car is more responsive.
I followed the ECU reset instructions to the letter and am very very happy with the outcome.
This was my first time doing anything under the hood and i had more than a little trepidation before I began.
I did get an MSCF error when I first started the car after the ECU reset procedure but it cleared when I next started her up.
This has done wonders for the car and my enjoyment levels have returned to those experienced when I first purchased the car 11 years ago.
Good luck to all!
