S2000blur

Alright guys I'm stumped I have no clue what to do first code popped up saying crank sensor b or timing belt side I replaced this then it popped up sensor a for the bell house side so I waited a week part came in put it in cleared the codes got to start it up and bam cel is on for sensor b again. It runs like a scallded dog till it gets up to temp then it'll go into limp and not go past 2k rpms. I need help guys it's driving crazy it's my daily and have been fighting this issue for several months. If I can't fix it I will be forced to sell it
