Help with engine performance issues
Ref; 77' 2.7 CIS - I've got this engine running ok except for a couple issues I still need to resolve and I need a couple of opinions on these points...
1) When warm, the engine hunts at idle. It has gotten very warm here in the high desert so I need to check a/f mixture and possibly lean the mixture a little bit. Also check the usual suspects; fuel pressure and WUR specs. Anything else I'm missing?
2) Any opinions on replacing points with Pertronix? (Other than having a spare set of points if Pertronix goes). Also, if I do this, does that eliminate the condensor?
3) Plug wires - I have the stock wire set on the engine. Why are they shielded and all other brands aren't? If I want to replace them what wire type (not necessarily brand) and specs should I look for?
4) I also have a random miss (occurs under decel and accel). Actually, it is a "drop out" more than a miss. The tach will indicate it. I have replaced the CDI, VR and AAR. It still occurs. Obviously I will dealing with fuel issues on point #1. Any other things I may be missing?
Thanks all for your input.
