Hi, I just recently replaced my fuel injectors (with my brother's help) with remanufactured ones. We couldn't get the fuel rail off without removing the intake, so we decided to clean it and the throttle as well. Now the car starts right up and sounds great at higher rpms, but once it drops to idle speed it dies out. Recently had a tune-up (about a year ago) and was running okay other then hard starting (bad injectors, per my mechanic) We've gone over everything and conclude it's probably the ECU, but I'm hoping we missed something that I can fix at home. Any advice would be greatly appreciated!

Thank you for your time! - Becca

You didnt bump the Throttle position sensor or mess around with the IAC module when you were cleaning the manifold?

Make sure all wires are hooked up you may have a intake leak. Did you re-use all your gaskets, the IAC gasket should never be reused, nor should the EGR valve gasket. The intake manifold gasket can if it hasn't been wrecked.
