CMPs are new, I put the GOSS ones in. And you are right, if the
CMP goes bad, the VCT goes back to base timing as a fail safe from what I understand.
With the
CKP, I was wondering if it could be playing up at start up (either not giving the correct signal, or weak signal) but once started, it goes good. But sounds like it either works or it doesn't?
Every 1 in 10 or so starts, it fires up first crank. It does feel like fuelling issue or some sort, but I'm getting good power once she starts, which then puts a bit of doubt in my mind.
Anyhow, I'll leave the
CKP alone for now. Have to remove A/C compressor to get to it on the 3v!
