I have a 2005 Trailblazer LT with 130k on it. The problem with it is it has no low end power just high end. If I'm at a stop sign and floor it, it takes off like a turtle. Bad mpg. Also with AC on and idling I get ALOT of lifter Chatter, like it's under a load. Hook my scanner up to it, has no stores or pending codes. I checked the load on the engine and it's like 60 to 70% load at idle with ac on and in gear. Only around 25% load at idle in park no ac. I done a tune up back in March, new plugs, clean throttle body, Sea-foamed. Did back pressure test, cat is fine and checked and tested the front O2 sensor.
I'm at a lost to what it might be, any help would be great! Thanks in advance!
