Definitely your throttle cable. It's binding & throttle freeze up sensor is kickin inMy m7 is acting weird, for the first minute or so it runs fine but when if gets up to temp it won't idol below 2500 it just stays their until I go again then it starts cutting out when I let off.
I took the muffler off when I was looking for problems and found that it is bone dry inside, is that a problem? When I cleaned the power valves it was oily. I'm wondering if I put them in backwards could that be my problem?
If it is could somebody send me a picture of how they are supposed to be.
