Do you recommend bosch super 4 spark plugs for a 1999 opel kadett 200iS 8 valve?

Question edited for clarity, spelling and to add maker. Why are you typing in all CAPS, it is rude and considered SHOUTING. Plus it is harder to read.

Your Diktator Management System is a snake oil product. Opel are quite competent at designing and managing your engine. It is supplying more power to the coil in the hope of giving you a better spark. Contact them and ask them what coils the recommend?

You must have a vacuum leak check a black tube leak close to the upper intake

any of these immobiliser/fuel pump/ecu /
needs a diagnostic tool to find the cause

the car still cranks but some immobilizers cut fuel and spark

Buy a copy of the "Vauxhall TIS" dvd from eBay. These have wiring diagrams for all Opel cars

Hi Donald,
I am actually having my cam belt changed today, I had to take my 200is to my mechanic as i am scared of messing up with the timing setting or bending valves as it happens with most motors. All I know is that you have to untire on of your side engine mounting, remove your waterpump system as it blocks the way, remove you timing covers, pullies and tensioners while making sure that your timing position doesn't move. They say its best to replace you cambelt together with your timing tensioners as older ones gives your belt a short lifespan.

Sorry I coun't help accurately.

My opel misses while I drive I replaced the fuel pump spark plugs did the whole motor over and stil the same what can it be?

disconnect the battery for more then 5min, or with the fault code reset tool. all opel dealers have 1.

what ever the grind you are after a low lift long duration is best
it produces more usable torque, prevents valve bounce
to get more performance there will be a loss of economy and the more power the less economy
basically fitting a turbo kit will produce a lot more power
the essence to cheap power is to get the engine to breath properly both at the inlet and exhaust
best talk with speed specialist engine shops as much can be gained for little cost it is put together right

do you have coil trigger on either wire to the coil? if so then apply 12 volts to the other wire to see if car will start.
