Ok, I replaced the ECT sensor, didn't help the problem. Now today, I start the car it revs to 1500 and then dies. Still have the lean codes. Could this be the intake gaskets? Would it start then die like that? Or would the car stay started if it were just a vaccum leak like that? I need help!


Thanks.
