I have a 2006 Monte Carlo. Has run like a champ up until February of this year. I have replaced Several parts and still have the same problem. Issue is that it will do a continuous crank but not turn over. Sometimes it will start, but then it shows "ENGINE POWER HAS BEEN REDUCED". Check engine light comes on. Code indiates Throttle Body Assembly. I have replaced that 4 times with used and remanufactured units. Car will start and run fine for as little as 2 days or up to 6-7 weeks then problem comes right back.

Any insight to problem is appreciated...
