First off I would like to say hello to everyone! Seems like an awesome forum. I'm pretty new to Fords and cars in general (only 17 years old).

Ok so here is the problem. I have 93 T-Bird thats got no 'get up and go'. She's a 3.8 V6 and the problem is that at full throttle she'll do 3000 RPM's at best. However in idle I can rev her all the way up to the 6000's.

Here is what I know/what I've done:

-The Check Engine Light is NOT on
-O/D Was slipping so I installed AOD-HP Shift kit from TransGo (did it all by myselft

)
-Tranny Flush/new filter
-Replaced Spark Plugs/Spark Plug Wires
-Oil changed (nothing milky, so head gaskets are good)
-Ran injector cleaner through the lines and all injectors are operational

Any ideas? Any help would be greatly appreciated. Oh and I don't know the mileage. The dash is stuck at 180xxx.

Also, how much power can you crank out of the Essex 3.8?

I disconnected the MAF (engine light ON) and it did pull much better without it. shifting from second to third gear at full throttle was a much heartier 3600 RPM's. So that means I should get a new MAF sensor? And is 3600 good? Hehehehe what can I say? Nipple twisting is fun

I'll probably be checking the codes later on this week and post my results. I was thinking that maybe after saving up some money I'll go for the Stage 3 Power Pack from supersixmotors.com. It seems to be very comprehensive and many forums I've visited recommend it. As for my gaskets, I'm just as surprised as you are. The guy I bought it from was kinda creepy so I was expecting it to have some problems but it drove all 30 miles back to my house. Still running strong
