| Since my Z has been "done" it hasn't idled right. Here are the steps that I have taken so far:
1) Boost leak test = No issues
2) Diagnostic codes = 55 no errors 3) New plugs (NGK Iridium IX Spark Plugs 8) 4) New FPR (and PSI is perfect and rises with boost in 1:1 ratio) 5) New Idle Air and checked OHM on Air Reg and took apart. All items are within spec and looked great. 6) I checked ground on MAF 7) New Gasoline 8) I have switched out PTU’s 9) I have adjusted my Z1 throttle bodies. To test their seal when the throttle bodies were off the car I put water into them to see how well they working. Water leaked out at about 1 drop every 5-10 seconds...it was the only "test" I could think of. 10) I have checked my timing and its @ 15 11) The car constantly feels like it has a miss at idle, however when I pull any 1 coil pack there is almost no noticeable change in idle...I have to pull 2 or more at a time to be able to tell a real difference. 12) I have Z1’s chip (EPROM) that is set to Injector Size: 850cc (I have 83 lb = 870 cc/min top feed injectors) 13) My Profile of mods is up to date 14) The car drives fine....it spins tires @ 60mph + and while under load doesn't appear to have a miss. 15) I did a compression check on the engine and it was low 150's across the board (built engine). 16) It will not staying running (at idle) on its own when first started. I have to bump the gas pedal to keep it from dying. Once it heats up it will idle on its on without dying, but still has the miss sound to it.
Here is a video of what it is doing. The odd thing is that the car runs great when I drive it just has the idle that climbs and falls.
Example starts at around 24 seconds in. [ http://www.youtube.com/watch?v=96xGc5M963c ] I am not touching the gas the entire time in this video.....this is what it is doing on its own.
The pillar gauges from top to bottom:
Fuel Pressure
Boost / Vacuum
Oil Temp
And one extra video [ http://www.youtube.com/watch?v=1EL54kHYMoc ]
I am out of ideas on this....any suggestions would be greatly appreciated.
