I've got an rpm surge when my car shifts from second gear (35mph or so). It shifts fine on the other gears and while boosting. Could it be my TC locking? I also just changed spark plugs and I read on a different forum that a guy had a misfire and he took off the plug wire heat shields and somehow that fixed his misfire. I was thinking about doing the same. Is this safe, and do they just slide off? Also when going to remove my O2 sensor for the back plug, I had to spray PB to break the sensor loose so I'm wondering if some of that got in between the wire and plug and caused this? Any help would be appreciated like always.
