caszboy Posted March 29, 2007 Share Posted March 29, 2007 OK, here is the deal. As some have been following i will update the scenario. As im driving around town. Every 10-30 minutes of driving the car will stall. Usually either at stop or right after accelerating from a stop. If i let it sit for about a minute or so, it will fire right up as if nothing has happened. It is easy to start when cold and runs great except for the stalling. I thought the car was starving from fuel so i droped the gas tank and the conditions of the tank were not bad at all. so i got a tank cleaner and poured it in and sloshed it around and now the inside of the tank is VERY clean. I also ditched the metal fuel filter before the electric pump and installed a clear one from pepboys. the filter is clear with some minor particles from the cleaner still working but nothing even close to clogging it up. I noticed last night that after the car stalled in a parking lot, The fuel pump was changing sounds. From Kind of loud to quite and back and forth. I pulled a spark plug today and this is what i found... Also i changed the dizzy to the 280zx E12-80 dizzy about 2 months ago. the car ran great for about a month after swapping. here is a picture. the dizzy has two vacuum tubes so i just plugged one and used the other. here are the carbs that i have, the webers. so after all that, here is the $1,000,000.00 dollar questions... - Do yall think it is the fuel pump? ( i have electric and the mechanical one is disconnected) - Do yall think it is the dizzy or the E12-80?...is it OK to just plug one of the vacuum lines and use the other one like i did? - Do yall think it is the weber carbs? - Does it look like it is running rich, lean or correct? I NEED HELP!!!!!! Quote Link to comment Share on other sites More sharing options...
