hi guys, well i have just put in my new injectors and stuff, and now have another problem, when the engine gets to normal temp its like the motor keeps trying to speed itself up, when cold it sits dead on 500, tho once warm the needle jumps up 2 about 1000 revs. what would this be, i have cleaned the isc with throotle body cleaner. i need a new filter but apart from that. what would you think???
