problems with my TPS reports

well my car was down for a few days while I sourced a replacement waterpump gasket.

during that time, I felt it was compelled to change some other things.

its a 96 se with traction control. I removed the traction control, replaced the TB [the housing has been nicely optimized] from a 99 atx cougar with the matching TPS/bracket/cable.

took it around the block and ummm, ya thats quite some throttle response... the car just skips over 1-3k in the rpm band... while thats mildly entertaining [ok heavily entertaining], thats not very practical for driving in traffic.

So I swapped the TPS back to the original 96, and the throttle still seems incredibly touchy [but at least 'safely' drivable].

I'm not sure what to try. insight would be appreciated [I have several spare brackets from different mtx's and atx's, different cables, and a spare gas pedal if that makes a difference]
 
sorry forgot to add that when I put the original TPS back in, its drivable. but the bottom half of the pedal is completely dead.
 
is it a mtx?


i do believe the atx and mtx tbs turn different ways. so if you put a mtx one on a atx tb it isn't working correctly because it engages differently.

I know the SVT tb turns different then the mtx tb based on the tps sensor. so I think its the same as the. the svt tb pull from the bottom and the atx from the top.
 
yes I am aware that the svt and non-svt turn in different directions [I've swapped that without issue on my cougar].

The 96 I have in an MTX and I've never seen this TB before but it has 2 rotating assemblies on it. The arm that attaches to the TB cable starts in an upward position and rotates towards the cable [just like the cougar atx's I am use to, the 3L's and svt's I've seen start in a downward position]. That arm is attached to another arm that actually turns the TB shaft.

This seems to be more of an issue of voltage readings of the TPS.
 
well in that case all I can think of is that the sensor was installed wrong and therefore not reading correctly.
 
BrApple, thanks again for helping me idiot check my work.

yes the TPS was installed correctly. turns out it just took the computer a considerable amount of time to adjust to the additional airflow [and for me to adjust to not driving the towncar]. 60 miles on the highway really took care of things. Engaging the clutch does now require more finesse than before because the RPMs still jump quite quickly and I can really see hating myself driving this through the first blizzard... might need to make this a summer only mod.

eitherway I still think there is a difference in voltages between the TPS. I have 3 spares I can swap between and I think my autotap will output this voltage reading... I'll be posting up my results.

edit, also has me real curious how the car would behave switching over to the 3L TB... will be giving that a try as well.
