Thread: Weird Drivability issues

The best thing to do is hook up a scan tool that shows real time data (i.e. Snap-On Solus), and take it for a drive. When the RPM fluctuates watch to see if the TCC is locking up or not. Also try enabling the lock up via scan tool to see if the fluctuation goes away. Not all tools will allow you to lock up, but hopefully you know a friend that has one that you can borrow.

I doubt that is the problem, but you never know, because it does it in park as well. It will do it when ever the car is not under load on declines, stand still, cruise or manual foot pressure. Above post might be on to something, because it all started right ater the belt, PCV and Air Filter change. Will be checking things out again. Love all the input, makes my brain work out of the box.

Well I'm not sure if it is fixed or not, but I think it may be. It turns out that there is a second o-ring on the PCV, pulled it last night and installed the second one. Tried to get the car to do it sitting in the garage and she ran like a champ. Will report back tonight to se if the .02 cent o-ring was the cause.

Awaiting report

Good deal! Glad to hear it's running well again.

And don't feel dumb, it was an honest mistake that was easily reversed. That's how we learn. Cheap/easy fixes are the best kind!
