thanks for the info kevin.
i did check the splice and it was slightly corroded so i fixed it, but
it still runs rough.
the next thing im gonna try is deox-ing the connector at the pcm, as a
just in case.
im not wanting to buy a new comp just yet, i was hoping someone had a
spare that i could try first before making the investment.
dan: i checked the compression a while ago and it was fine all the way
round. dont remember the numbers but they were all pretty close. within
10-15 psi of each other.
anyone else have any ideas??
thanks.
