malfunction

hello!!!! I have a problem with a Pontiac Sunbird 92, what happens is that it turns off when brake and then turn on again, change the DIS module and a coil, I do not know what the revulutions can be almost up to 2000/Hy then go down to normal, and when they go out they fall to less than 500/h.

If it only happens to you when braking can be an electrical problem, check this you have normally walk and disconnect the fuse of the brake lights, and step on it if it is not for it is an electrical problem, but you have the test first and let me know, I tube a problem like this on a kia abella and delay as 1 month in giving the corduroy warn and explain how to continue.

Thank you carnal, I'm going to do it even if I don't know what I pass !!!! "!

Look I recommend that you clean the idle valve, remove it and clean it with that spray to clean acceleration body and then lubrication with oil, see how it follows.
