Learn to cope with throttle movement.

ecm controlls your idle.

Could it be the 0.93 crossover tubes?

well yea thats gonna have something to do with it along with the injector, but the only way to fix it is to get a bigger vp i believe. You cant change the idle due to the computer control of it as far as i know. The truck is sucking more fuel at idle then the ecm is used to stock.

I would put the stock crossover tubes back in and see if that fixes the problem. I've never heard of to many happy campers after going with the 0.93 tubes.

OK appreciate it I mean it doesn't go into lope mode just does that then goes to normal idle but I sent my stock tubes back also
