My blazer is almost ready for the road, but I have a lingering issue. I've replaced the plugs, distributor cap, distributor button, and Idle air control valve all with OE parts. I've also scrubbed and cleaned the throttle body so it's nice and clean.

The engine doesn't want to start (but does eventually) and the idle is still rough. When I rev the motor (while in park), she sounds good but when she's returning to idle there's a loss of engine power and half the time it stalls out and the other half of the time she picks up into the usual rough idle.

I can take a video and upload it so you can see/hear what I'm talking about if I haven't given enough info. ANY help would be appreciated!

 

Did you make sure to plug the connector back in that is on the back side of the distributor?

 

Yes of course. I'll double check all the connections are secure tomorrow.
