Ok. Just swapped a new motor into my teg. 94 b18b. The car ran great for a day or so. Then while driving I started to notice the tach jumping up and down a little, but the engine would not fluctuate with it. After a little while it started doing it more and more, now it will jump all over, the car will start to bog, then die. It does this sparratically, but has gotten worse. I put a new fuel filter on, and did some basic tune up stuff but it didn't help. And just a couple minutes ago the speedo started jumping around to, with the car parked and at idle.

The MIL was throwing a code 20 (Electronic Load Detector) and a code 43 (Fuel Delivery System). After I put the new fuel filter in, I reset the ecu and now it doesn't come back on, but then the car doesnt run long enough for the ecu to detect the problem. (Runs at most 1 or 2 minutes.)

Any help or ideas would be appreciated, before I take it to acura and pay them hundreds of dollars to find out whats wrong.
