Default Low RPM Problem

I am having issues with the car running at low rpms. It only does it sometimes. When I start off in 1st or 2nd in low rpms from 1500k to 2500k it seems like the car falls flat on its face then when I give it alot of gas it seems to resist for a second then take off. It does it through all gears at low rpms. I dont know if it needs a re-tune or what. The car is a cam only car. It only started doing this when I had a new clutch installed.

How many miles on the car?? That can be useful info on where to start looking for ideas as to the cause.

Who installed the clutch --- any chance they did something to the PCM (like a dealer reflash?)

-or-

maybe its just the new clutch grabbing harder and you need to give it more gas?

Have not ever changed the fuel filter. Is there a write up on how to do that. Also it does not seem like its grabbing harder its more of a lag in the throttle.

There are many good tuners in the Houston area. PM me if you want the number to a few. There are a handful of things in the tune that could cause this problem.

Well I finally figured out what caused the problem. It was a O2 sensor unplugged but it never threw a check engine light until yesterday.
