[DnaProRacing]

This is a continuence to the arrrrrgh thread. My car is still bellowing black smoke and surging. it doesnt do it all the time, just once In a while when I get a little hefty on the throttle. I had injection service done, then got diagnostics done "only tossed o2 error" which I put a new one in, still smoked. was told map sensor, cleaned the old one out and put back in, still does it but not as frequent. so i put a new map sensor in, still does it, again not as frequent. what else could be causing this? pressure tests were done by pep boys as well as my usual mechanic and everything checks out good. block test, head gasket, manifold gaskets, everything checks out good. has new plugs and wires which were tested as well. oil level hasnt changed thru all of this either. I for once am out of ideas, my mechanics are all baffled. btw, new tps, iac, pcv, vacuum hoses, the list goes on. what else could cause black smoke when getting into the throttle??? ideas please? Im so flustered, if i wasnt bald, i'd pull my hair out!!!
oh, it doesnt toss any codes now either...

btw, the name DnaProRacing is from my old online racing days. I ran a team of drivers against other teams. In no way does it mean I am a mechanic. Im learning as I go. This is a new found love "working on my cars". and you guys have taught me a lot...
