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
http://easywatercar.com/kayakosupport/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=131 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.
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.
its the alternator pulley thats defective and in order to pull the alternator you a have to take off the piece with the hoses on it above the alternator and you can wiggle it out
