Did it just start doing this?
Sounds like a cool set up... if it has just started acting up.. it's likely a sensor failure casuing a lean condition at part throttle... Are the O2 sensors working properly? Remember, these babies tell the ECU what to do with the fuel curve... the increased output from the larger injectors may be skewing the exhaust O2 readings and hence the ECU is compensating by trying to lean out the fuel curve... of course it would have been doing this all along.. it all depends on when it started running poorly.
btw... I really need one of those GT40 lower intakes for a 351W... Ford no longer offers it as it has been discontinued..
Any help would be appreciated.
Good Luck
