CEL codes p0121 and p0122, need help

[eclipse97blitz]

I'm getting these two codes and the car is running like ****. I've replaced the tps twice and still having problems. Is my pcm going bad or what? NEED HELP. What is causing these cel codes?

thanks

A faulty MAP sensor can cause P0121.

thanks for the reply, tomorrow I'm going to get a new map sensor and see if that fixes the problem. i check the wires from the tps to see if any melting has accrue. they seem fine from what i saw. i also replaced the front o2 sensor. I'm having a big problem with the car running really lean at times. and really rich the rest of the time.

i replaced the map sensor and it seems to have fix the fuel problem, but I'm still running more rich then I did before. I've purchased a apex AFC and will install it to help even out the air fuel. again thanks for the help

well it seems I'm still having a problem when i first start driving the car, I'm getting popping noises coming from the exhaust. first and second gear are the worst. put it seems to get better as i drive. after awhile it seems to go away, I'm still getting the same cel codes. I'm sure thats the problem. and it idles find at first then it goes up to 1500rpms and I'm running real rich all the time.

well i finally found the problem, after taking out my intake pipes and moving some wires i found a spot where the wires leading from the pcm had been touching the block and had melted the 3 wires going to the tps. so i fix it and now the car runs fine.
