i changed my radiator the other day due to a crack. car fine for about about 20 minutes and then it stalled. now the car runs very rough and stalls if i dont keep the rpm's above 1500. drove it around and it was jumpy and had no power untill rpms got up. it was smoking heavily.please help

 

jacob, its hard to say without looking at your car first. But, I would say check the MAP sensor vacuum line. When this pops off, it usually resluts in poor idle, and tons of black smoke. I disconnected mine to see what would happen, and it wouldnt run at all. So, check that. Its the little black box on the drivers side firewall with a connector and a vacuum line going to it. good luck

yep, check the map sensor.. it is next to the brake master cyl on the driverside firewall.

 

thanks guys-that was my problem
