Idling rough and low at start up

My Suburban is idling rough and low (300 rpm) at start up, and running a little sluggish at first. Recently changed fuel filterand fuel pump. It isn't throwing any codes. Someone suggested the TPS. If so where is that and what should I do. Thanks in advance!

Check with problems with idle air control valve/actuator. This is supposed to kick up rpm when there's a heavy load on the power system, such as A/C.

Starting off truck is sluggish but slowly gains rpm then runs fine


SOUNDS LIKE YOU NEED TO HAVE YOUR TIMING CHECKED. EVEN THOUGH THE TRUCK IDLES FINE IF THE TIMING IS OFF BY ONE DEGREE IT CAN CAUSE LOW POWER.

Did you properly gap the plugs when you changed them? Improper spark will cause really rough idling at low RPM like that.

Rough idle


I took mine in to change the plugs and they said there are four O2 sensors in the fuel mixture system and two were bad. I didn't replace them since they were a little pricey ($500 to replace both) and I have 103,000 on the car. Has very similar roughness and occasional oscillations, but no stalling. Hope this helps.
