Cylinder 2 misfire 2000 Toyota Corolla 1.8

2000 Toyota CorollaHave to give gas to start and continue running. I have cleaned idle control and changed plugs and coil packs. Reads cylinder 2&4 misfires. It has been sitting unstarted for a year. Previous owner said it started sputtering going up a hill and died. Has been sitting since.


One possibility is the Idle Air Control may need replaced. The most likely cause though would be a faulty intake gasket or blown head gasket. You can test for both. The most common being the intake gasket.
