in the last week i have installed a superchip and a svt throttle body. it ran great for a couple days. all of a sudden my car started not t acelerate like it used to. it feels like the secondaries are opening at 3,000rpm and it doesnt want to go past 4,000rpm. i checked the throttle body and it was opening correctly and i tried my car without the chip and it still ran poorly. please help!

i have a 1996 contour lx, V6, ATX

Might be a problem with the secondaries not opening.....Check the imrc and cable.

What is / Where is the IMRC?
Any picture?
