Hi brothers and sisters I went to my country for holidays so now in Al Ain UAE.
Problem I'm facing is really hard as I'm an electrician technician I could'nt make it 100% but better then before. Some problems I got and made it those made my car better in its power they are: small leakage of air from intake manifold to throttle, because of old hard rubber pipe lines, the one pipe line from engine head cover to throttle it was leaking too this will send few oils to intake manifold on pistons that's really needed for good performance of engine. Others foul filter is was little blocked I already changed new one. Now it's more better but now I'm thinking to clean all injectors for good performance.
I hope this all will be helpful for my brothers and sisters.
Please Note one thing in this car, if you want to change the engine control unit in any reason so don't buy used even that is in good working position. Because this control unit has included security system. If you did so its will be lock. And the old one can be program of security just once with a vehicle that already done. Only new control unit can be program with your car's security system. I bought used and tried its got luck so as I'm a technician I have opened unit and changed air flow and air temperature sensors by soldering. I took just those sensors from used unit and repaired my own engine control unit. Now the fault of air tem and air flow sensors are gone. If you can do this of better to buy new control unit that's cost you too much.
Thank You for reading and good luck
