I have a 94 155 that has failed is mot due to poor emissions. In an effort to overcome this I've replaced the whole exhaust under the advice of a main dealer but still no use, has anyone any suggestions
Hi Tom, to diagnose whats wrong I really need to see the failure readings. Could you post the readings on here? I specifically need the HC's, O, Lambda reading and CO and if the fault is at 2700rpm or idle. Thanks and I hope I can help.
