Hay guys my baby is A 94 cam LT1 with march underdrive pulleys moroso intake granatelli mass air 52 mm throttle body edelbrock intake edelbrock headers magnaflow cat flowmaster cat back just to name a few. She idles at about 800 900 RPM but wan I get stuck in traffic she gets A lumpy idle and the amp gauge goes with the idle hanging in the red. Give A little gas and bring up the idle and Shes fine (I don't want to ADJ the idle any higher to like 1000 rpm) I was thinking of just putting the stock pulleys back on. But power master has A 200 amp alternator I was thinking of getting. (A stock alternator is 140 amps) but do you need 200 amps and with the under pulleys isn't that counterproductive but I don't know more amps MORE SPARK right??? tell me what you think

 

Hows the battery????? At normal idle, voltage at the battery should read around 13.8~14.2 volts.....

 

Now that you say that. That battery is about 4 years old thanks ill check it. THANKS!!!
