I got a engine code that there is a problem with the Intake Manifold Runner Control . What is this ?

Do the cobras have IMRC butterfly valves like the 2005+ GTs do?

My 98 COBRA has them. Only a few year COBRAs recieved them. This helped the numbers in the low end range. Removing them with either a delete kit or removing the butterflies yourself will hurt your lower end a litlle but if you have power adders you can make up for it.

IMRC controls the butterflies on the intake manifold. The valves remain shut until a pre determined preprogrammed load then the IMRC opens the buttlerflies. Its a control box mounted under your intake with 4 bolts. You will have to take the intake off which is good cause if its acting up you will most likely need to clean you IMRC plates.

if the IMRC is not opening the valves when it should could that cause a miss fire ? the other trouble code im getting is p0300 ( random / multiple miss fire )
