I just got home 5 mins ago, took some time looking my car over just to see if I could find something. The problem occurred while at a stop sign, I slowly accelerated like I always do in town and about 20 ft after the stop sign I heard a soft pop and all my acceleration just died. At first I thought I had destroyed my transmission but I stopped the car and put it in reverse, that worked, then tried drive, it worked but I had to just touch the gas. Holding the gas down any further would result in the engine revving up but the car not moving, like it was in neutral, but if I touched it lightly it drove enough that I could get it home. Any ideas as to what is wrong with it?

I've had lifter knock for about 3 months, it's on my LONG list of things to do, but I was trying to get my other car running first before I took the top off of my GP so I could send the supercharger off to get rebuilt before I buttoned it all back up. Would that have any effect on it or is it an isolated problem? I know the cat is bad, that's another thing on my list to get replaced. Sadly I have more problems than I do money.... Any insight would help out a lot guys, thanks for your time.
