Hey all,
Having a problem with my 01 S-10 W-code 4x4... at idle it has an intermittent miss and then if i mash it to the floor it sputters until it catches up and then will run fine.. will also miss occasionally while under normal driving conditions eg. highway or speed limit in town... just put brand new AC Delco platinum plugs, Wires, Cap and Rotor and had the ignition module tested.. it tested perfect.. i have also changed the air filter and cleaned the mass airflow sensor. if you have any ideas please toss them my way because i am at a dead end here.. Thanks in advance for your help.

How is the fuel pressure and fuel filter?
Does the check enine flash when missing ?
Any check engine lights on?

I would get it on a good engine capable scanner.
Check fuel trims and check history past and present for cylinder miss and see which cylinders are missing.
Also check camshaft retart setting.
