Ok. After scanning here is the codes:po205/injector circuit/open-cylinder 5; po300/random-multiple misfire detected and po305 cylinder 5 misfire detected. Po300 is because maybe before scanning I removed one by one each coil pack and find that cylinder 5 is not reacting (not working)I thought it's coil pack, I bought new but I returned because it was the same. Mechanic check and he said that coil pacs are good. He thought first maybe injector from cylinder no:5 or o2sensors(he find that two o2 sensors not working ok, they not changing their numbers they working flat. He checked injector and he found that is ok. Now he saying 90% he is sure that ECM is not good. There is no ground on cylinder no:5 and that's why he is not working properly. Ecm cost $400 new +$80 programming. What do you think?Go to the dealer or buy some used ECM or ask for another opinion?Is possible that ECM causing the problem with cylinder 5. If Ecm is not good why is not same for all cylinders?
