Hey guys I noticed that with my RB it studders in a higher gear, at lower speeds once I get past a certain throttle percent, just really slight hiccups, almost like its getting too much fuel.

Also around corners sometimes, it likes to cut out like its not getting any fuel, and also after a WOT run.

I also hear fuel dripping in my gas tank after i turn the car off for about 15-20 seconds or so. Could my fuel lines be loose that connect to the fuel pump in the tank? Also could the positioning be off reason for it cutting out under corners, WOT, and going downhill sometimes?

Thanks

I had the exact same problem with my RB, and I could never figure out what was causing it. I changed the plugs and it did it less often.

I have a friend that has the same problem with his RB, I think it's a common problem.

Where is Carl H? He is the RB god

sounds like your blowing out the spark, could be an indicitation of too big of a gap, try lowering gap, or try an ignition amp like the hks or aem, or even new coil packs or epoxy the old ones
