Hi,

When my car is warmed up, 99% time when i release throttle the idle shut at between 200-400 rpms and come back at 800-900rpms. Sometime a backfire will come... someone has an idea??... car has basic bolt-on.. intake,tbe,fuel pump, 3-ports, tune...

i did some search but didnt find the same problem.

Maybe its related to another thing.... i need to change injector because at 23psi @ 5300rpm my stock injector are full loaded and i begin to run lean.. 1000ID are on the way...but maybe its related with my idle problem?

thx to take some time :P
