[QUOTE="Black Gold 380R, post: 16676073, member: 70025"] Okay, The saga continues with good news and bad news LOL. The good news is I got my radiator filled with fluid and added my radiator overflow hose. No leaks detected. I then reinstalled my ALT. The bad news is I will not be able to take the car out for a test drive today as it is running WAY too rich. I think I found "A" problem. My wide band gauge reads an A/F ratio of 15 (very high, which seems correct). My ECU is reading the A/F ratio as 12.5 (where it should be, but that is obviously wrong as it is pouring black smoke out the rear). I thought I might have a bad 02 Sensor. So, I swapped the banks (meaning I changed the computer from the left bank 02 sensor to the gauge 02 sensor on the right bank). I started the car again and it read exactly the same. Gauge said 15 and ECU said 12.5. So, the ECU reads 2 different 02 sensors on 2 different banks as 12.5. So, I think something is set up wrong in the ECU as it should not be running that rich at a 12.5 A/F ratio. It seems the 15 A/F ratio seems more accurate to me. I can't even get it to run long enough to make any adjustments as it fills my garage with black smoke LOL. My wife said I came in the house reeking of exhaust LMAO! The good news is while it was running I pushed my clutch to the floor and put it in first gear. The tire did not turn with the clutch disengaged. I slowly started to release the clutch and the tire began to spin. So, my clutch, transmission, driveshaft and rear-end all work great. No noises, no grinding and no rubbing. At least that went right today LOL. If I could just get my A/F ratio right I think it will be awesome. I will probably need to take it to a performance shop to have my fuel injectors uploaded as they are not listed in the ECU profile for initial start up. Then I will need to figure out why my ECU is reading the 02 sensor as 12.5 instead of 15 like my gauge. Here are some pictures I took today. It's been a while since I took pictures without the fender covers in the way. Engine bay is looking awesome. Too bad it doesn't run as well as it looks LMAO!
