Ok so I've been working on this project for awhile now with the help of a few people and just the other day we got it started. No vacuum lines were hooked up the first time and it idled fine, the next day we hooked up all the lines and it idled like crap. We replaced spark plugs, and adjusted a screw between the injectors to get it to idle below 2000 RPM's. Next day we finished a few small things *mainly zip ties and removing the heat shield from the stock turbo b/c it was in the way of the steering* and the car took off fine from the shop to the gas station. After filling up with 91 *like I normally would* I left the gas station and shifted into 2nd with no problem and then into 3rd, and thats where it happened. The engine lost power *as in it wouldnt rev any higher* and I was forced to pull back to the shop I had just left. All the connections and wires are fine and strong but the car wont go above 3500 RPM's. Also it seemed that the more boost that I let in with my Greddy Boost Controller the worse it got. Its not the MAF, because while I am not moving I can rev it to the max with no problem, but put it in gear and try to go and it seems like its trying to cut off the fuel. And as in the title of this post it is running very rich. Does any one have any ideas on how to solve these problems? I am out of ideas.
