just recently bought an '82 ZX. I drove it today for its first real outing. On my way home from work, I stopped at the inspection station. I was out of the car about 10 minutes, enough for a good heat soak. When it was restarted, it was loading up, black smoke coming out the exhaust and missing. I had to move the car, and a couple minutes moved it again, still the same. When I was finally ready to leave, about anohter 5 minutes, it was still loading up, maybe not quite as bad. When I pulled out, it bucked badly, popped and then cleared up. I made several more stops along the way and no problems. I am very familiar with newer american fuel injection, but htis is my first dealings with first general computer controlled FI. I have done some work with older mechanical injection, but anyway. Any ideas? Sound familar to anyone?

 

Yeah, that happened to me once awhile back. It never happened again, so I don't really have a solution for you.

 

I chased that demon for a long time. turned out to be a combination of a weak fuel pump and a bad Air Flow Meter (AFM). try doing the rebuild procedure spelled out by JfariladyZ in the "AFM rebuild" thread here in the tech section and see if that helps.

Rod.

 

stock EFI SUCKS!! hehe
