Hi All,
Posted before about the slightly wonky idle my car gets, and came tot he conclusion 'they all do that, sir'.
However, the car is definitely holding back at light throttle, most noticeably when cold. In addition, there's definitely a slight misfire on idle.
I'm thinking probably coil pack? Although I'd expect that to be worse under load (it's fine under heavy load, at full throttle, and mostly when warm, although it does sometimes seem to slip into a bit of a miss on warm idle)
No problems with car getting up to temp, not noticeably rich on idl or bad on fuel, so am eliminating CTS and stat issues.
Plugs were new <1k ago
Anything else it could be other than coils? I'm loathed to buy either eBay cheapies or a SH set as I don't know how good they'll be, and I guess the only real way to check is to swap out with a 'known good' set.
Car is an 03 172 cup, BTW, 69k.
