hey, i have a problem with my 3rd generation rx7... there is no spark from the top two spark plugs, but they are new and in good condition! Also the car is hard to start up and then puffs out black smoke. It seems to have lost most of its power, and won't idle...the rpms just drop and the car shuts off. The car also shakes vigurously....any suggestions to what is going on and how it can be fixed?

thanks for the support!

 

Start with the vacuum line to the MAP sensor - this is the sensor on the firewall just above the oil filter. If that vacuum line comes off, the car will run poorly if at all and will smoke badly.
