I am having a issue with my focus and when it starts sometimes when cold
Most times my car starts first time but i will say 2 in 10 times i turn the engine over it struggles to start and i have to press the accelerator to fire it up.
My car had a new yuasa battery recently as the old battery did the same thing when starting sometimes.
Its like it can't fire up by itself, and odd times when i start the car, it starts straight to idle line around 750rpm, if i can explain this better... right when a car normally starts it revs up to around 1500rpm and then drops down to the idle level, but mine doesn't always do that, it turns over and doesn't rev, i also notice i have to rev the car a bit to get the car normal again. as the accelerator pedal doesn't feel responsive and after a few revs its feels normal again.
I have cleaned the throttle body and its made a slight difference but nothing significant. The car is well maintained so has new air filter, fresh oil and filter. Iridium plugs.
Could it be something to do with the accelerator pedal or something along those lines, also when it struggles to start i get quite a strong smell of petrol, could it be over fuelling.
Or could it be related to the coil and stuff. even though i have changed all that already
Anyone got any ideas.
