Re: tuning a misfire out of idle? HOW TO??
well now when i go to sell my car the buyer is going to be super sketched out. if i were the buyer id think there is something wrong with the motor. but its in perfect shape, ill just have to explain to him/her

could be, i think my alternator has been on the fritz for a little over a year. over 5500 rpms my battery light turns on...LOL
im too cheap to swap it out and see if a new one takes care of it :1

it is definately ignition issue, as I posted in the other thread about the diffent plugs I tested in my motor, and the colder I go the better the car idles, I am using uberdata with rc750cc, and gm 3 bar map sensor.

You can do two things to get rid of the popping when using bigger injector.
1 - Richen up the mixture a little
2 - Take out timing until it goes away.
The bigger the injectors are, the less accurate the ecu is when controlling low duty cycles. The injectors flow becomes erratic at such low duty cycles. Saturated injectors are crap when it comes to this. P&H injectors correctly used with P&H drivers can operate correctly at low duty cycles.
