help rpms wont drop!

Went through the same high idle problems that you described including running lean. Idle would stick at 1500 rpm and idle down after goosing the throttle a little. Very annoying. Got all the same good advice from the RBC but nothing worked. Even went to the point of buying 60 lb. injectors,new aeromotive fuel system, and adding lots more fuel to try and correct the lean condition. Actually made the situation worse. Modern Performance finally found the problem while checking and comparing cylinder temps. Number three was running hot--hot enough to burn out the header gasket. Seems that the fuel injector has two little electrical connections that when plugged in make the injector fire. One of these was bent and caused the injector to fire sporadically -- if at all. Because the air/fuel is read from the drivers side this came up as a lean condition. I could have dumped half of OPEC in the motor and still would not have corrected the condition. Spent lots of money trying to fix this and lots and lots of frustraton. Thanks again to Modern Performance for finding the problem.

Thanks man but theres been further investigation and developments. Found out its my throttle sticking, for some reason the throttle body is not allowing the throttle cable unit to close all the way to 0 rpms. Going to dodge tomarrow to get a little help trying to fix this. Tried to call x-metal about the issue but got no call back so i guess im on my own for now trying to tinker with the x-metal throttle body, who knows might be the spring?

I would never take that truck to dealership. You should try to fix it. Don't give up. Even if you have to put the stock TB back on.

there is two things you can try bo

1. remove the TB, loosen the screws holding on the blade, and postion it equally around the inside, so that a thick piece of paper fits all the way around.

2. if it doesnt then a small amount of sanding may be required to achieve this.

then reset idle.


I am aware alot dont work on there trucks, so jsut give this info to the dealership, as long as they dont sand too much, you have to be very carefull not to leave too much of an air gap
