okay under load and this is about 90% of hte time the car surges and or hesitates, like fuel is being completely cut off to the engine and it starts to make a popping noise
it is intermittent, for example leaving work today it ran like a gem while ****ing aorund with my buddies vette, but i got home parked it couple hours later took it back out and it ran like crap about, surging and popping noises and what ever else... its under and kind of load it happens but under WOT it will not happen as long but under partial load somtimes it just keeps going so i have to let off and push the clutch in....
say im rolling in first gear... at 2500 rpms the car will start bucking like fuel is just being cut off
the Pump is new
the Cap Rotor Plugs are new
this started happening shortly after my Exhuast was put in. i did run the car for a week with out O2s just had hte holes plugged because i was waiting for the extensions in the mail... and it just got worse and worse till where it is now that i just know when i hit the throttle and let the clutch out the car is just gonna pull the same old BS.
