Have it scan tested, sounds like the transmission is not shifting due to inop. speedometer. Needs to be looked at right away!

A friend of mine replaced my speed sensor and that wasn't the cause. He thinks it might be a cluster sensor but wasn't sure if that could be the culprit for to being able to acceleate.

Did both problems start at the same time?

Yes. I remember because I was at a stop sign.
And i meant that he wasn't sure if it was the culprit for no acceleration.
Update: The problem turned out to be corroded wiring.

More than likely it's your speed sensor located on your on your passenger side of the transmission. I just changed mine and it's working jus fine. If you jack up the passenger side And take off the tire you will see it.
