CCA has absolutely nothing to do with the charging system. Charging system could care less about CCA as that really only applies to the starting system and the amount of time the starter can be cranked. What you need to be concerned with is the output of the alternator. BTW...and this is for anyone not in the know...CCA means Cold Cranking Amps, which I believe is rated at 0*F (though someone will definately clarify that if I am wrong)

Your dips and near stalls could very well be caused by the lack of available voltage and/or current. Our coil packs love power...our cars get finicky if available voltage gets to be below 11 volts, near-worthless at 10.5.

In any event, I would either isolate or eliminate the charging system first. It'* probably one of the more simpler systems to troubleshoot in this scenerio.

On the flip side, if your idle dips below 800 rpm'*, the charging system should throw a voltage warning, and cause a poor idle.

Questions:

When was the last full tuneup (plugs, wires, PCV, both air and fuel filters)?
How old is your O2 sensor?
Have you ever removed and cleaned the throttle body and IAC/passage? See Techinfo on that.
Have you ever checked your ignition coils? See Techinfo on that.

Either one of your symptoms could be the cause or the effect.

Well I understand CCA ana all just want the bonney to have what was required for a baterry and living in Canada gets cold in a.m. I am in a more desert type region actually so no more than -10 f but to answer the Qs I have owned this bonny for 2 weeks if that so I have no idea about any of the suggested replacements I assume not done car has 78 000 kilometer = 48,467miles as this was car hardly used by previous owners as far as i can tell. I bought off a lot as it came in on a trade a from Mercedes Benz dealership. So I didnt get the owners manual any suggestion re thgat ? as well I just want to keep this bonny alive for the next 20 years best car i have ever driven and I have had alot of cars I really am going to film my problems building the site now on livevideo called 1993SSEi i am terrible at typing out what i want to say
