The problem is that when my car is ticking over or doing about 2mph then the engine management light flicks on for about 2-5 seconds. It will then go out and i may not see it for a few days. Ive heard off few people that it could be the lambada sensor. Im not running a cat by the way. Any one any ideas on what it could be???
> engine management light flicks on for about 2-5 seconds
then I doubt it would have logged a fault code, usualy it will have to be on for more than 30 seconds. Anything less and its considered intermitant, ie just ignore it. When the car losses performance and the light does stay on, then thats when you can start to do some proper fault finding.
Can only be a few things
1) lose connection to fuel injector 4. You need to remove that latge long black box that runs along the back of the rocker cover on the c20xe/let to disconnect the plug. However when you do this, you also disturb 1, 2 and 3. Clean all the 2-pin contacts and reseat.
2) injecotr 4 has an internal fault, replace. However it is recommended you repalce ALL 4 injecotrs in a set rather just the one.
