well my car starts real rough not getting enough gas i'll assume cause if i don't rev it a little it won't start. it dies in reverse. after i have it warmed up it won't start until after 5-10 times of cranking it i'm not getting cel codes for anything nor a light. i don't know if it's a vacuum leak or what but it's very aggravating and i'd like to fix it asap. when it starts to do this not getting gas **** if i just let up on the gas some it'll still go but i can't ever let it even go half way down. here's a video of it running i fixed the idle part for it though. and it's a pretty stock z6 just intake and y8 mani

Does the CEL work? What car? What ECU?

 

yes it works, ej1 and whatever stock is i think p06 maybe p28.

 

The D16Z6 should have a P28 ECU. Check that.

Is there bright white spark at all 4 spark plugs?

Do all 4 injectors pulse fuel?

Have you checked the mechanical timing?

 

yes i'm getting spark in all 4, i don't know how to check if all four are getting fuel, and yes i'm in time.

 

You need to give details about how you checked spark and the mechanical timing.

Remove the fuel rail, unplug the distributor, and crank the engine to check spray of the injectors.

Have you measured the fuel pressure?

 

well i put a screw driver in each spark plug cap, and i checked TDC on crank pulley and cam.

 

Have you measured the fuel pressure?

 

sounds like one of your injectors is stuck partially open and its getting flooded at start but being starved at higher rpms

 

i don't have a the tool to do that so no.
what's away to check that/fix?

 

You may be able to rent a pressure gauge at an auto parts store.

Have you checked the ignition timing with a timing gun?

 

In the future, please include this type of basic information in the first post of any tech thread you create.

 

will do, as for checking ignition timing no i'll have to rent the tool for that too. i've put my dizzy at all the way advance think that could anything to do with it?

 

Rent the timing gun and pressure gauge and then go from there.

Also check whether all injectors spray fuel.
