    Hey guys havent posted in a while, just a quick question. Im still pretty new the the GTP but i've had the car about ehh 4 months now and over the past week or so i have noticed a gradual but steady powerloss, now its getting to the point of concern. Not sure if it could be possible bad plug or tranny slippage (The car JUST went over 100k miles yesterday). Just wanted some input on here, you guys have been Fu**ing awesome at helping me so far. thanks again

    are the rpm's going up and your not going any faster,(that would be tranny slip) or when you give it gas it falls on its face with no power? (this could be a clogged cat) or even a clogged air filter.

    what year is your car? and no check engine light yet?

    No check engine light, i installed a new cat about a month ago. its a 2000. Well i give it some gas, hesitates just a bit then goes, the RMPS may just go up just a hair before it catches but nothing like when my trucks tranny went out.

    Try getting it scanned. Even with the cel not on it can still have a code. Try cleaning the maf sensor.

    Try cleaning the MAF, the Throttle body, and the air filter.

    could even need just a tune up if your over due, sounds like engine, not trans.

    check your fuel pressure as well, along with the rest of suggestions.
