when the car is completely cold and i start it.....it will start fine and thien like 2 min into the warm up the car will shake a little bit...then once the cars is warm it stops. only lasts for like 2-3 min......any ideas what causes it?

 

Perhaps you plugs fouling out a bit during warm up.

 

mine will do it too as most i've heard, i think the plugs need changed

 

I had this EXACT same problem and replaced the following tryimg to track it down:

Fuel Filter
Water Temp Sensor
Vacuum Lines
Vacuum Check Valves
AWS Solenoid
Cleaned and Flowed Fuel Injectors
Spark Plugs
Spark Plug Wires
O2 Sensor

I also blocked off the EGR because I was thinking that the EGR valve might have been getting stuck

After that, I was still having the problem.

I eventually bought a replacement (used) ISC and installed it at the same time I installed a Power FC. That finally solved the problem.

Try replacing the ISC with a known good one and see what that does.

 

mine does it even after new plugs and an oil change...

 

will i have a new fuel filter. brand new 2k miles ago. all new vac lines. i guess ill try the plugs.
