you don't appear to have knowledge about vehicle repair/s..........

I would suggest you get the repair manual for this vehicle and with some other training material get a better understanding of this...

the one thing that is possible would be the EGR as this messes up when in gear moving....with your desciption this is just a guess...

I know about cars enough to work on them this problem i cant figure out

well how do you explain the fuel filter in backwards ? you had a 50% chance on getting that correct..

so what do you know about EGR valves...how is this controlled ?

I would replace all wires and coil that are arcing. If this doesn't solve the problem unbolt both converters between the motor and converter and move appx. 1/2 inch apart. If this solves the problem buy new converters.
Advance Auto and Auto Zone will scan your engine for codes free.
Feel free to post the codes for help.

I was at work and let sumbody put it on i checked it wen i got off and it was backwards and yes i know the egr gets stuck on sum cars and its vaccum controel by the egr solenoid

One converter is hollowed out the other is cut but still in tact and i replaced the wire were it was arcing and it is still arcing in the same spot i am going to get an ignition coil tomorrow and im goin to change the transmission filter

You might want to check the insulation resistance between the terminals of the Opti distributor cap. A test of the fuel pressure might also be helpful.

HOW DO U CHECK THE insulation resistance between the terminals of the Opti distributor cap????
