hey guys on my 94 camaro two cylinders are not fireing what could be wrong ive changed the two fuel injectors for the cylinders 1 & 2 that are not fireing it helped alittle but still only running on 6 cylinders and really shaking at idle?? please help me???any ideas

 

First thing I would check is the plug wires. Then I would make sure there is no corrosion in the opti terminals to those cylinders.

 

can this be something series or just with ignition??>>..thanks
