 I've read through the archives and have a rough idea where to start but I 
thought I may get some input for you all.

The car takes on cold start either  a long time to start or it starts acts 
if its got bad plugs and either runs or dies.  Then when you restart it 
after the shaking goes away rpms are normal and car runs smooth with no 
misses.

When car is hot it will start but its a Bit** to get it started.  Now if I 
give it some gas while starting it, it starts right up.

I belive I have bad injectors. Both pumps are running and are not unusaly 
loud.
Alway run preium gas, and I have tried differnt brands/ and stations. No 
luck there.

Here are the most recent things done car has 199,000 on it.
fuel distributor has less than 50K on it.
Cap, Rotor and wires have 98K on them.
Fuel filter has 15K on it.
Plugs have 15K on them.
I recently had new rocker arms, valve springs shimmed, timiing chain,rails 
and tensor.
Dealer said that its hold fuel pressure to spec.
Just replaced EHA valve-seemed to help a lot.
Dealer put all new fuel injector O-ring seals and cleaned injectors-Note 
these injectors have about 100K on them .  I replaced the first set.

On occassion, when you give it gas it hesitates as if got a bad cap and 
rotor, I have not inspected inner contact points for wear or corrision. Its 
rare that its does this I've only had it happed about 5 times in the course 
of a couple months.  It was not raining when this happend.  So, I think 
moister is out.

Any suggestions?

Thanks

Jason
