Alright well i just installed the pettit tkt intake and removed the air pump and installed underdrive pulleys the alternator, tension one, and the motor one and now my car idles very ruff and it will not hold a charge.....

i was wondering if my alternator is going bad or because the alternators pulley is larger now it is not being spun enough to charge/keep the battery charge or should that not even really make that much of a difference

because the last 2 days ive charged the car the whole night and then by the end of the day it almost doesnt even start because its lost the charge

idk give me some of you thoughts

thanks

Rough idle after removing the airpump is common if your still on the stock ECU. Do a search for airpump removal.
Have you had your battery tested? I think Advance Auto and AutoZone will test the whole charging system for free. It might be something simple.

 

That sounds like a dead battery than anything else.

Get your alternator checked - Autozone for example will do it for free.

i just replaced the battery the old one was dieing after 4 or 5 days

 

would it be easier to just put the air pump back on or block the smog system?

 

Were you having any trouble with the battery before the Pettit under drive pullies ? If the new battery is doing the same thing as the old battery then you alternator isn't doing it job (have any idea what voltage the alt. is putting out) when your driving ? If you had a problem with you alt. before the pulley kit then it will ge worse with the under drive especially if you do allot of around town as opposed to highway driving I've found mine falls off (voltage) below 1k rpm with the under drive

 

yea thats exactly what happens its deff the alt


now i just need to know how to get rid of the idle problem

what else do i have to do to make it stop idling bad can someone please explain in detail or send me a link to where someone has before

thankss
