I'm wondering if a malfunctioning IMRC could cause bucking/hesitation during acceleration. Basically, if im cruising in any gear, around 2000 - 2500 rpm, if i give the car more than half throttle she will go, but there will be bucking/hesitation until the secondaries open. My question is, if the IMRC were bad, could the secondaries open too early? And if so, would it cause a problem like that?
I'm trying to rule out the problem being the clutch...rpm's don't skyrocket as if it were slipping, though i've never had a slipping clutch before. When the hesitation happens, the rpm's do not rise or keep rising. I've done the "4th gear test" and the car stalls right out.
Sigh...
