We'll I thought I had the problem licked. But I still have this low end bog, it hesitates and begins to excelerate then it takes off. It acts normal until it shifts then bogs a little then goes agian. I have a cold air intake on the car. I do hear this whistle like a vacume leak when it quits, then that's when it goes. I've never heard that whistle before.

Heres what I done.

I've replaced the intake manifold gaskets because of a leak. I took the air plenum( the upper intake) and washed it out with water and power clean. I had a lot of carbon build up in it.
The injecters were filthy, are the little black ends supposed to spin when you turn them? Three of mine did but the other three were stuck. I used carb cleaner on them and all of the ends broke free except one. I used a pair of plyers and eventually it broke free. The weird thing was that the plastic end was off set and that's why it was stuck. This either happend at the factory or while it has been on the car. I've never taken it apart. I don't know if this could have anything to do with it.

I also changed the spark plugs and wires. I used autozone spark plugs (7mm) and autolite platinum plugs.(.060 gap)

These were the few things that I've done that I can think could have caused any problems. I know there is a sensor in the air plenum(the upper intake with the throttle body) could it have been damaged by the cleaner?

one last thing I started the car after we finished, pulled it forward adn then changed the oil. I noticed that when the oil was changed towards the end it looked milky. I didn't run it but just for a minute. I've checked the oil agian and it looks fine.
