Spoon Posted August 18, 2007 Report Share Posted August 18, 2007 I swapped out my 2.8l for a 3.1l the idle is fine but the engine stalls as soon as the gas is pushed. used wiring,egr,ecm and throttle body from 2.8l, any ideas. Quote Link to comment Share on other sites More sharing options...

Spoon Posted August 18, 2007 Author Report Share Posted August 18, 2007 I drove the donor car around for a few days before I removed the engine, ran good. no codes are showing up. Quote Link to comment Share on other sites More sharing options...
BXX Posted August 18, 2007 Report Share Posted August 18, 2007 You are still using the 2.8L EGR, right?? Also, the 3.1L has different ECM programming than a 2.8L.... Think of it this way, the 3.1L is gonna want a bit more fuel. Check and see if you have any codes currently... Quote Link to comment Share on other sites More sharing options...
