Title: Bad surge
Post by: capitlj on May 08, 2008, 11:27:37 PM
When I launch hard or if I take a corner a little too fast without a  near full tank of gas the car surges something fierce.  the launches especially it'll go good for a second then its like i take my foot off the throttle, then it comes back on again, then dies out again.  I have gotten it to surge like that about 4-5 times once.  i'm thinking its a fuel issue because when the tank is full it works fine.  Any ideas??

Pump going bad? Perhaps the sock fell off the pump pick up?

Yes but I only had that problem AFTER the HO swap. :hick:

With the old 5.0 SO (which he still has) I could run with 3 gallons of gas and floor the throttle with no stalling. This was with 3.73 gears, 2.25 duals, and a HO upper and TB. The SO doesn't have enough power to cause the full throttle stall that I experience with the HO

The only time I ever had a problem in my old HO powered 'Bird was when the sock fell off the pump.  I noticed it mostly when power-sliding around turns like a jackass...it would die, mid-slide, and then the car would come back to life after it straightened out.  I wouldn't be suprised if 98% of the people experiencing this problem had a fuel pump strainer sloshing around the bottom of their tanks.
