Hi, I was wondering maybe someone here could help me. This car has a slight
hard starting specially when warm.
When starting cold in the mornings it starts at first try, but weak,
hesitates at first but very soon comes strong. Later, after two - three
hours beeing off, with engine T° around 60°C, it starts at second or third
try, hesitating. But on the other hand, when it has been off for a short
while, say 15 min, it starts at first try and strong.
The car has 90k miles on the clock, spark plugs, wires, cap and rotor were
replaced recently. The fuel filter has 6k miles. The fuel pump and fuel
accumulator have never been replaced. The cold start valve works fine, I
think, I removed it and squirts fuel when the engine is cold, although I
don´t know if it is the proper amount.
I did a search and found out that maybe the fuel accumulator cant keep
static fuel pressure for warm startings (vapor lock), but if this is the
case, I wonder why the symptom appear on mornings, engine stone cold, and
cold start valve squirting fuel.
Otherwise car running is almost perfect, the only other little problem is a
slight unstable idle when warming up.
I would appreciate any idea.
Thanks in adavance.
