I just replaced the TPS, do i need to reset the computer. Also it said i might need to adjust the new TPS but i installed it and it seems to idle fine and drive good in all gears. Thanks Danny

 

You didnt mention the yr of your car. My 88 Formula is non adjustable, but I did adjust it with some ingenuity. I cant remember the actuall reading it should give out but I think its something like 5.6 volts or something in that area.

 

in the idle position make sure its under 1.25 volts i like to set mine much lower though and it makes more sense to do so like at .750, if i remember correctly it has to be up past 5 for wot.. now i cant remember dammit.. it might be like 4.5 volts

this is important because if you arent going past the prescribed amount of voltage for WOT the car never goes into power enrichment mode... that basically means you have a richer mixture and more aggressive timing.

 

Idle tps voltage should be 0.54

 

thats quite a bit low for most of the TPS sensors on TBI setups

that sounds more typical for TPI setups and even then it might be a good idea to set it higher on them on MAF cars to avoid the dreaded code 33

while its possible to get it down that low and still get past whatever it is for WOT (i havent looked it up its around 4.5 if im not mistaken), its definately not the norm. Only paying attention to the idle voltage is a mistake, you must ensure that TPS voltage goes past the prescribed WOT voltage at WOT to enter power enrichment mode. Idle voltage is not so important except that it should be set below the voltage that would set off a TPS high code (1.25 volts) and as a general rule of thumb should be set on the lower end of the scale (while still enabling WOT) so that you have as much TPS resolution as possible.
