blazer wont idle long
 

My blazer has sat up for the better part of 2 years with me only cranking it a couple times of year. I recently dropped the tank and got rid of the old gas,replaced the filter, cleaned the screen in the tank, and added a couple of gallons of premium gas with some fuel system cleaner. It fires up fine and runs as long as the accelerator is pushed down. I'm pretty sure that if I got it on the road and ran it real hard for a bit and blew it out it would straighten out because its worked in the past with this vehicle. My question is is their something I'm overlooking that may help the process?

Fuel injectors or the Spider would be the next logical step after what you have already done.

Well I changed the plugs out today and I'm going to do the wires tomorrow. It's running a lot better at idle but still choking down on acceleration. I ran some sea foam threw it today and it seems to be having some affect. I'm pretty sure the injectors are gunked up and I'm hoping the sea foam runs it course. Is there anything else you would recommend besides breaking down and pulling the injectors?
