Anybody got an idea???? I have a fiat punto 55 on a "p" plate... Before Christmas i had to replace one of the coil packs due the fuel injector warning light comming on and the car started to run poorly.. Result all fine.. $ weeks later same problem.. Have replaced Plugs,Ht leads, 2nd Coil pack Incase And even swopped around packs incase that 1st new one had gone faulty.. But no change.. I have run redx through the system. The fuel injector light does come on but goes off after the usual few seconds.If anybody can help then thanks.

Hi if you are still getting the injector warning light comeing on it could possibly be being caused by the Lambda sensor or the map sensor. but also look for any perished or damaged vacum pipes as sometimes problem is caused by air leeks. Would also try running redex of an injector cleaner through your system if thats not already been done. hope that helps you.

Could be the ECU. see this guide

Thanks Marti155 did not think of vacum pipes but feel that this is not the problem but will check anyway.
