Hi! everybody this is my first post but have being visiting this site for sometime, got a 1995 micra with cg10 engine and auto transmission
problem 1 is it takes time start have to crack the engine for a while then it would kick in.
problem 2 is when the fuel is at 1/4 tank then sometimes it will lose power and then die out start again it will start put on the accelerator it will pick up speed very slowly. thought of telling this; the person i bought it from didn't had the fuel pump mounted on the right place it was hosed up and left on the bottom of the tank but it is submerged..................i changed the spark plugs, solered the TB and also cleaned the dizzy cap.....................please help.
