    think my thermostat is screwed

    Like someone else said, make sure your fan is cycling properly. Sounds to me more like the fan not coming on. Good air flow on the highway but none when you're driving in town (no fan). If the thermo were stuck closed or part way closed you'd run hot on the highway too.

    Suspension Help!!!

    You shouldn't need any parts to correct bumpsteer! From the Maximum Motorsports site: BUMPSTEER Bumpsteer is the toe setting of a wheel changing as the suspension moves up and down over bumps, or with body roll while cornering. There is a myth that the tie rod should be kept parallel...

    If all the above doesn't get you there, remove the LCA ball joint nut and knock the ball joint loose. This will let the control arm swing farther.

    What's the best way to fix up the suspension?

    I believe what is being talked about are the off-set bushings offered by a number of suppliers. They actually raise or lower the rack and pinion housing which helps to reestablish the correct geometery of the tie-rods.

    Exhaust ?: What is drone?

    One theroy is that the drone is actually the tail pipes resonating like a pipe on a pipe organ. 'Graham' on the Corral Forums site did some research. It just so happens the primary sound the engine makes at 1800-2000 rpm is just the right frequency to get the tail pipes resonating. This happens...

    QUIETEST MUFFLER - What is the best 2.5" quiet muffler out there?

    Do a search for "exhaust drone is fixed". Follow the links to the Coral Group site/post and read about it. Don't listen to the BS thrown up by people who haven't tried it. I had a custom exhaust guy install the side branch resonators on my GT and it works! :nice:

    Did anyone find a solution to the.............

    I had a hard start problem when the motor was hot. The dealer replaced the IAC and all was well. Of course I had to take it in three times with the standard "...can not reproduce the problem" results before I got them to believe me. :bang:

    MRT Cat-back - Anyone have one? Questions...

    So far no one has answered his question. The majority are just bashing MRT. Sorry, I can't answer your question about the cat-back either :shrug: , but...., I got to put in my 2 cents on MRT. I have their catted mid pipe and MagnaFlow cat-back on my '02 GT. I live where they use salt to...

    another octane question

    The long explaination.... A higher octane rating means the mfgr has actually added compounds to the mix to slow down the flame front (burning) of the fuel. This is done to prevent "detonation" or "pinging" or "spark knocking" usually associated with high compression or SC'ing or hot weather...

    Hesitation when starting when engine is warm

    I had a similar problem with my 02GT where it didn't want to start right away when hot. It would crank for 3-5 sec's be4 starting, but not all the time. It was still under warranty so took it to the dealer. They replaced the IAC and it seems to be working fine now.

    Anyone here hate their exhaust sound?

    I hated the 2000 rpm drone from my MRT catted mid-pipes and Magnaflow cat-back. Then I installed side-branch resonators I read about over at Corral Forums. They killed the drone. Now I have a nice throaty growl that howls nicely at WOT. :nice:
