Hey another noob question. How do i take the throttle body off? we did like 4 or 5 bolts and it still wouldnt budge... were workin on it right now so anyone with any quick help would be snazzy! Thanks!

 

On a SOHC you remove a small screw for the cover, take that off, remove the throttle cables and electrical connectors (TPS and IAC, I think) then you should see two bolts (maybe 4, this is from memory) right on the top of the throttle body. They should be pretty long. Once you get those out the throttle body lifts right out. A manual would be handy.

I doubt DOHC is much different, If that's what you have.

 

SOHC, and i got it! thanks, the throttle cables had two bolts and the two on top, the first time we went at it, we were dumb and didnt take the throttle cables off and didnt see the bolts down there! any who its off and being cleaned! Thanks

 

Alright, so if I decide to swap out my MTX TB for a ATX TB, would I need to switch to TPS and IAC sensors for the larger TB?

 

well, i would think that your Intake Air temp sensor would not have to be changed and either would your throttle position sensor, but thats just a guess... i'm interested in doing the same thing to my neon, so if anyone knows, please post. thx.

 

The sensors do not have to be changed, however you will want to change the throttle cable cams. If you don't, you will get a really jerky throttle feel. At first it won't do anything thing, so you press a little more on the pedal, and then bam its like all hell brakes loose. So then you let off quickly and the car falls on its face, so a little more pedal and the process keeps repeating itself until you get up to speed. A real pain in the butt in city traffic.
The easiest way to do this is to remove and swap the entire linkage assemblies as a unit. To do this you will have to remove the throttle plate. When you put the plate back in remember to use the ATX plate in the ATX throttle body because common sense will tell you that the MTX plate is 4mm smaller. Believe me, I have seen this happen many times. "talk about high idle". Also remember to "brad" the bottom of the throttle plate screws when you reinstall them so they will not back out. After you have them reinstalled, just take a punch and crimp the backsides.
Hope this helps. I have done six or seven of these swaps with positive results every time.

 

Ah, good times!!!
