[s-cars] High boost miss - Spark Plugs??

[Walsh, Edward]

Hi Mihnea:

- Plug connectors are new and all have 5K ohm resistance
- Idle is smooth
- Coil pack ground is clean
- Power is good until >1 bar
- Miss is subtle, but prevents boost from hitting 22-23 (MTM 1+) in all but
second gear, boost fluctuates from 17-20.5 in 5th gear
- Miss is most apparent when engine is COOL

Thanks, Ed

Hmmmm, even if the plugs are fine, did you test the
plug wires (or whatever their real name)???

They are commonly known for causing high boost misses.


HTH,
