Hard starting
Hi I have a opel corsa 1.4is 2001 model. I have a pain in the butt problem with my car. In the morning or when ever during the day when I try to start my car it cranks very long and then eventually starts and runs rough for a while then starts to clear up and runs perfect can smell feul as if its overfeuling. Have no performance problems while driving. I replaced the cambelt,crank sprocket (keyway_crank pulley) feul pump(bosch) feul pressure regulator. I am sure the timing is correct. Also replaced the temp sensor under coil. Tested the air flow meter and so on. No vacuum leaks. Anyone please help.
