Today I have checked the imrc, when I start the car the cable moves and stays there, when I Rev the car past 5k revs the cable doesn't move, is it suppose to?? I think my MAF sensor is causing a problem to. I don't know if there is any newer codes but then I push the accelerator it takes a moment then the revs rise and drop slowly?? I forgot to mention that the post cat lambda sensor is not in the cat, a mechanic friend of mine said to test the cat we should take the rear lambda out and if one of the codes disappeared then we knew the cat was broken? With the rear lambda out I gained power back but I've soon lost it?
