2001 Opel Vectra some problem with gear up

First of all thank you for your attention, I m gonna to check the faults again with tech 2 and inform you as soon as get them.

Thanks

As i've checked the fualt again with tech 2 to get the erros code I faund out that it can be related to plugs as the computer mentione d missing wires error for all 4 cylindres. It means the replacement spark plugs dosen's suit engine power.

Wouldn't be better to replace spark plugs and put a stonger sets instead?

We've replaced spark plugs with the main ones but the problem is still running and the rpm doesn's exeed 4500 and diagnostic computer (tech 2) mentions error ; missing fire on all 4 cylindres (1, 2, 3, 4) (but not any error code).

Just replaced the plugs and not coil but I cant check the crankshaft sensor it works properly or not could you please help me to check it?

I've replaced the coil pack with a new one but position sensor does not match the engine do you have any refrence number or figure of the part?

We have replaced both coil pack and position sensor but problem still remains and rpm doesn't exeed 4000 could you please help me and tell me what should I do else?

How can I reset the computer?
