Nadeem, have a technician scan for trouble codes to able better diagnosing, Possible fuel safety shut off if vehicle equipped.

see repairman

A code P0304 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector, Burned exhaust valve, Faulty catalytic converter(s), Running out of fuel, Poor compression, Defective computer.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs/wires). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if equipped). Otherwise, check the coil packs. Sometimes the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your catalytic converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

P0200....Injector Circuit
Now what would cause this i have no idea offhand with my head under the bonnet sorry

First thing to do is inspect wiring harnesses in the engine bay as from early 90's to 96 all wiring had a biodegradable insulation (forced to do so by US) that breaks down over time and heat to reclaim the copper. If you inspect yours and the insulation is crumbling they must be replaced as they are shorting out. Codes mean nothing till this is checked/replaced.

c'est la tete pour quois?
