my ecu isnt sending a pulse to the coilpack yellow/black wire. would this mean my ecu is knackered? as my car has been running on 2 cylinders for a while and trying to get to the bottom of it. is there anything else i could check? i had a egr valve gone a few months back and blanked it, i also thought i had a coilpack gone which i had changed 3 times but never worked. could any of these 2 things effect the ECU if it might think its still faulty maybe? as i was told the egr runs 2 of the cyclinders which are down. I was also thinking about putting my mates ecu (same engine) into my car to see if it works as i dont want to splash out money on a ecu which is alot of money that still doesnt cure the problem. but im not sure if you need to program them to your car? could i do a straight swap?
if my ECU is down then anyone recommend a cheap place to help me? or somewhere around bristol?
