i have swapped all coils and injectors from left to right. checked compression, smoked engine for vac leaks and still the problem is cylinder 5? anybody seen this before. doesnt show up as misfire on snap on solus scanner, but cylinder 5 is the main one on cylinder contribution test causing problem. gonna check fuel pressure. in meantime just seeing if someone has seen this before and can lend a little insight. thanks in advance

P0353 indicates an electrical fault with cylinder #3, not 5.

It will be the coil itself, the spark plug, the harness to coil 3 (often the connector at the coil), or the PCM.

i understand that, not getting any drops on 3. all is normal with 3 but 5 is showing the drops. got this code before swapping everything and got it again after swapping. so if it was the coil it would have moved correct? also have checked connector and performed wiggle test while running.

Did you clear the KAM or reset codes after moving the coils around? Is it a pending code, active code, or stored code?
