Hey, my car sometimes idles very rough from 3,000 RPM and back down to 2,000 RPM then it just stops and idles normal @ 500 RPM. Kinda weird. But while it idles like that, it shoots out black smoke signaling im burning gas. Ive been getting these CEL codes.

Code 6 - Coolant temperature
Code 15 - Ignition output signal
Code 16 - Fuel injector

I have ordered some new DPFI injectors from people to see if it fixes the problem. However, how do i fix these? Thanks.

Easiest way is to just replace the coolant temp sensor (code 6), and replace the ignitor (code 15). The coolant temp sensor is located on the side of the cylinder head under the distributor. The ignitor is in the distributor. Replace those parts, reset the ecu, and your codes should be gone.

 

Thx much Redline that was the exact answer I was looking for.
