MAJOR FD PROBLEMS< HELP
Sorry this post may be a little long,
I had bought my 94 FD with a new engine with 30k miles on it, the car has a Greddy catback exhaust and some kind of intake(looks like Apexi but im not sure). When i bought the car i was aware that it had the common Oil pan leak problem and i had planned on getting that fixed. However after maybe 3 days everything went wrong. I was showing the car to a friend and was going to drive it with him in the passenger seat. I backed out of the garage and tried going forward but the second i gave it acceleration past 3k RPM the car started to jolt back and forth. It was like it wanted to stall but couldnt, and so i decided not to push it and backed off, surprisingly at very low speeds the FD ran ok but any higher than 3k RPM i would see problems. My first thought was to check the oil because of the oil leak.I was right in that the oil was very low. I bought new oil and put it in and after i did i noticed a puddle of oil on the floor, so the oil leak is a problem but not the biggest. After putting in the new oil i started the car to see if it would work properly and after i did huge amounts of WHITE colored smoke started to come out of the exhaust. As i gave it gas there would be more white smoke. I decided that maybe the oil needed to circulate so i took it for a drive around the neighborhood at very low speeds. After waiting a few days the car is still in the same condition. There is hesitation at 3k RPM, WHITE smoke, and the oil leak. Something else i noticed was that the intake looked as if it were soaked with oil!!!?? I could see something dripping from it, I dont have any idea what to do, im planning on taking it to Gotham Performance to get it checked out but does anyone have any other info or have seen these symptoms before? Im thinking the 3k hesitation has to do wtih the turbos but that doesnt explain the jolting of the car, please i need help.

the 3k hesitation sounds like your car is in limp mode ( for some reason) you may need to reset the ECU, do this by taking the negative battery cable off and holding your foot on the brake pedal for about a minute ( this bleeds off any leftover electricity in the car), then put the negative cable back on the battery and try it out.
The white smoke could be that you have accidently pulled the Fuel Pressure sensor tubo off the throttle body, this is located between the firewall and the upper manifold on the drivers side, you should see a little black box with 'pressure sensor" or something like that written on that , it has a plug going to it but also has a small black tube that runs to the side of the throttle body, make sure this is connected at both ends.
If it aint any of these then I'm out of ideas, sit tight, someone will contribute, or do a search
good luck

huge amounts of oil in the intake? turbo seals gone or i know on fords when the pcv system was clogged and not venting it would reverse pressure and suck the oil into the intake but these cars dont have a crankcase so...
