Hi, what do you mean by chugs at 48 mph ? Doesn't it go any faster then 48 mph, does it lose power, bog down when you press the gas pedal to the floor. Does it have a misfire , that makes the vehicle buck and jerk ! Is the check engine light on or any other lights for that matter ? How many miles are on this trailblazer ?

    I can excellorate and it will pick up speed. It just thugs as if it's running out of gas. If I speed up/slow down it goes away. I just bought the vehicle yesterday. The mechanic had put a remote starter on it before I picked it up. This wasn't noticed when I test drove it. 140,000 miles

This Jeep starts missing (chugging) at about 45 mph. What would cause that? Replaced plugs etc.

run the fault codes. check the serviceability of the cat converter as it may be broken inside and blocking the exhaust

I looked down and the speedometer in my 05 Trailblazer said I was going 120 mph. When I stopped and put the car into park, the speedometer stuck at 70 mph. I need a simple, cost effective solution. Please...

This is a very common problem with Trailblazers and is caused by a fault speedometer stepper motor - the actual motor that makes your needle move around is wearing out.

You have two solutions, if your Trailblazer has 70k miles or less you can take it to your local Chevy dealer and they will replace it for you as part of a recall.

If you have over 70k miles visit my Trailblazer speedometer page here:

The co2 was at 14.6 for both the hc was at 48 at 15 and 70 at 25

being that the co dropped and hc rose at 25 mph, it looks like things are getting leaner, the first thing i would start looking for would be unmetered
air, such as an intake leak between the airflow meter and throttle body ,or dirty airflow meter.
he next thing i would look at is spark advance.
the c02 looks pretty good to be a cat. but might be a possibility.
top end cleaner may be a shot in the dark.
