no idle for motor unless a/c is switched on, motor dies when put in to neutral manual gearbox. any place to look for problem?

the idle air control valve would be my starting point :)

Mine [before I bought it] had issues with a relay of sorts up by the brake booster, try that and/or any other relay.

put new plugs and leads, #2 plug was not in properly oil coming out passed plug, causing misfire and lack of idle, adjusted idle screw lightly after work done, solved problem, put polymer into oil to help seal any leaks from inside the motor. went for a good run, performed great, the plugs where all loose, I think previous owner forgot to torque them to correct spec. Now I know they are done. Gives me a lot more confidence to drive her anywhere. water system completely renovated professionally GT Autos Auckland, did a brilliant job. idle air control valve given throttle body cleaner solution works well. thanks for all your help
