Stock heads, large cam,stock intake, 30lb injectors....all together make for a bad combination of parts..I don't look at the TB as a factor in the problem..but rather the hole of parts you've compiled.aleborjas said:i have 75mm maff, cobra computer and i have a chip but not on i am goin to try it is diablo!
i have a large cam!
Michael Yount said:aleborjas - give us more detail -- all you changed was the throttle body? You didn't change anything else at the same time? Are you absolutely certain you got everything hooked back up/plugged back in the way it was supposed to be? Was the throttle body new? In addition to checking your initial tps voltage (you mean .98?) did you open the throttle to see if it climbed smoothly to 4.5V-5.0V at w.o.t.?
The only way you should've lost any power OR drivability with that swap is if you forgot to connect the throttle cable.Every Explorer and Mountaineer ever built came from Ford with a 65mm throttle body --- it should work just fine on yours, top end and bottom. Something else is wrong - it's not the throttle body causing the problems.
did you get the cobra computer on purpose? Most go w/ the A9L because it has the best fuel/spark curves for the 5.0. I'm not saying that's your problem, but just curious.aleborjas said:i have 75mm maff, cobra computer and i have a chip but not on i am goin to try it is diablo!

ups sorry 4.66volts at WOTPoopDawg said:3.66 volts is not correct for WOT, it should be close or at 5 volts. Sounds like a problem to me....
but i told the guy who made the chip all the things i have camshaft etc......DMAN302 said:19's yes for sure, but the chip should go on ebay, not in your car. The chip is a general tune ment to increase the timing for better performance on a stock setup...your best off bumping the timing yourself to 14-16* provided your not pinging. The RPMII is a BIG BIG intake made for big displacement high reving engines...your set up will not be able to take advantage of it at all.
