this has been going on for along time now but its been bugging the sh*t out of me. my fuel rail was leaking gas bad. so i replaced the o-rings. im not sure if before the car was lagging, but i noticed after that the car would lag at 2k and then pop out of lag and go. im wondering if maybe i have tightened the fuel rail to tight, or whats going on. anyone that can shead some info on this problem would be more then helpful, thanks

 

Did you fix the fuel leak?

 

ya fuel leak is gone, but i think since then car has been lagging, and not letting as much power out, as before

 

Car, engine, mods?

Last tune up?

Ignition timing?

CEL codes?

Fuel pressure?
