TPS problems

I have a 94 5 speed and my check engine light always comes on. I've had it scanned and it said the problem was my TPS and my MAF so I replaced both and it still comes on. Sometimes when the light is on it runs fine but other times it hesitates when I accelerate and then when I clutch to shift the rpms go up even with my foot off the gas. I was hoping having the codes cleared on it would fix it since both parts are new. Has anyone else had a similar problem?
 
Do your rpm's go WAY up? Like 2500rpms? Or just a little? If way up, when my IAC went bad I got all kinds of ghost codes from the MAF, TPS, and O2 sensors. Replacing or checking all those didn't fix problem and it ended up being the IAC. I had weird howling sounds in cold mornings and dying goose honk when shutting off the car before it went chernobal and starting idling at 2500 + rpms and huge smoke from unburnt fuel out the tailpipes. Just a thought you may rule out.
