my car has 19.5k 05 viii with flash as only perf. mod.
also has several electrical acces. incl second amp and boost gauge.
recently it hasnt been starting on the 1st turn in the morning.
second turn seems to start it but its getting more reluctant.
perhaps the battery is going bad? any other guesses?
i also park on an incline if that matters.
thanks in advance

 

whens the last time you changed the plugs?

 

i thought spark plugs were good til 60k... Any suggestions on replacement plugs? aftermarket or stick to the oem. I'll run a search on this now. thanks

 

NGKBPR7's is what I changed from stock plugs. Recommended for light bolt ons = me. no problems so far.

 

Probably either fuel or spark, could be lots of things though like a leak between the maf and the turbo inlet. Replace the plugs and see how it does. Also make sure that maf pipe is sealed up good on both ends (turbo side and airbox side)
