Technical Cleaned throttle body - now juddering & engine management light is on

[RDM13]

Hi everyone,



First post in here as its my first major problem with the car after owning it for 2 years!!



Removed the throttle body today to clean it using air intake and carburettor cleaner. Once it was clean I fitted it again connecting all the sensors etc but it started juddering. When I tried to drive it became worse with short spells of loosing power. Engine management light appeared so turned the car off ... Any suggestions would be amazing?



Thanks!

Hi,


are the sensors electrics connected properly?


also the problem you may be having is that the ecu is thinking the throttle body is a new one. The ecu will adjust to the throttle body getting clogged but when its replaced it needs relearning to the ecu. You can try a throttle body relearn via multiecu scan and hopefully this will help with the issues your having.
