I want to give my 99' 3.3 Grand Voyager a little more grunt for not much $$$....so I found a 3.8 58mm throttle body at Pull-a-Part from a 98 T&C 3.8. Got it all cleaned up and bolted on to only find out the gasket from the parts store dosn't seal! Comparing the two throttle bodies mounts and surface area are identicle except at the IAC passage, where the 3.8 (left) has a larger passage and will leak around the smaller gasket.
I tried several parts outlets and only came up with the same gasket for 3.3 and 3.8 liters, dispite being different. I'll call the dealer in the morning but I want to see if any others had this issue?
Thanks
Matt
