As I let off my throttle petal, my 1993 Mercury Capri 1.6 (non-turbo) decelerates instantly, in a jerky action. I there an adjustable regulator for this problem? Thanks, J Kelley, FL

Your throttle position sensor could be bad. Try finding a used one at a junk yard, they are +$100 new if you can find one...Chris

Have 1992 capri non turbo when it gets hot it acks like it floods out and shuts down then you have to wait a couple minutes with the gas pedal to the floor before it will restart replaced the o2 sencer but...

This may be electrical. The ignition control modules commonly get heat sensitive on the capris (its happened to me twice), causing car to shut down at hot temps. Replace the igniter at the same time, bet this will fix it. Igniter is inside the distributer, module is on the outside of the dist..good luck...Chris

Where is my IAT sensor? I bought a X2 Module and they do work because my friend has one and dyno showed an increase from 228hp to 256hp 
If its the air temp sensor removing it or unplugging it MAY do a few things depending on the type of sensor it is. Most send a signal to the computer in terms of resistance (ohms) that changes with temp. That signal is used by the PCM in conjunction with others (MAF O2s MAP) to determine timing and fuel requirements. If you unplug the IAT sensor the computer (on most GM cars) will see an open or infinite resistance and give the lowest possible temp input to the computer for air temp. That can increase timing across the RPM range sometimes giving a few extra ponies. It can also lead to detonation if too much timing is present.

I hooked up a 10k ohm potentiometer to my IAT sensor so I can dial in the temp I want. If I want some timing ****** for nitrous I dial it so the computer sees 185 degress F and it takes 2 or 3 degrees total timing out. For more timing I dail in 20 degrees F and it will advance it some. Works good.

This may be totally different on Capri but most IAT sensors work the same. As for changing the reading on the IAT will not give a 28 HP difference since the ECM will only give a given default and P.S the Potentiomete is about $6.00 for a good one at Radio Shack.

Where is my IAT sensor located? Its a 1992 Mercury Capri non Turbo. I bought a Performance module and its splices into the two IAT wires. Is

Save your money and don't attach the module, it does not work. It only works during idle and after that the O2 and MAP sensors take over to control the air fuel ratio and timing. Take note that if there is a conflict with the program to your ecm's parameters, your engine will run under limp mode default which would result in less HP and performance. Good luck and if you need ore performance just spend the extra to have your car Dyno Turned.
