the problem is that you switched from automatic to manual and the computer is looking for the trans connections and electrical components. it can't go to closed loop like it should

put the automatic trans back in or have it rewired for the manual an d computer reprogrammed for a manual. no it won't hurt the engine it will stay in open loop all the time and will not pass any emission test s if it's required in your area and your gas mileage will be bad.

Thank you will try the rewiring and reprogramming the computer to the manual gearbox. Will inform you of the results after a week.
