performance question

[bbbarker]

Hey guys need a little help on a problem with my '06 yukon with 108,000 on it. when driving using less than half throttle it feels like something is holding back on power. hard for me to explain, but it just feels like its being held back like its not pulling hard, and i have to give more throttle than should be needed. any and all help will be appreciated.

Not knowing many details, but have you checked your cats? A plugging exhaust will take away power over time...

no, haven't checked the converters. how would i go about doing this? does kinda feel like my cherokee did when the cat was clogged in it.

I believe the quickest way without dropping them is to take an inlet and outlet temp reading.

check to see if your floor mat is under the pedal from everyday use. its happened to me before and i noticed a difference when driving around and when i straightened the mat back out, worked fine.
