Low revolutions Mazda Allegro HB Falla does not give min

Hello, hopefully someone has the knowledge and willingness to help me

I have a Mazda Allegro HB 1600 Model 1996 I have 2 problems (presented at different times) with rumato and the mechanics have only done to get money without result.
1. For 2 years. For times and especially on warm days, the revolutions begin to go down and upload, almost until it goes out first and then until it goes out at intervals of 3 seconds approx. I have to upload the passage of gasoline with the screw so that it does not go out because if I release the accelerator in a curve or a stop I remain without direction and without brake. No mechanic has found the problem.

2. After a change of retainers and packaging, a failure came out at low revolutions; that is to say while accelerating or in the lower part of each change, after when instead corcovea and in general it does not run out as before. He was changed to everything, spark plugs, high installation, valves were calibrated and nothing, just an Arctic after getting out of the workshop.

Bot a little smoke while it is cold but compression is not low, however it tends to reheat uploading and I have to manually turn on the second fan.

I really like the cut of the car and I hope someone helps me to rescue him. My thank you in advance.

Hi, I am Anyer from Colombia, you have to say that packaging changed you, sifue the blog or cylinder head cover, if they lacked by overheating you have to suddenly change the cylinder head for the reason for compression when brushing the cylinder head has to open prelimers for the relationship.
That is the first point,
the one that goes out in minimal you opens the passage to the El Accelerator screw because this is of injection and the only way of controlling the gasolimna pass computer sensors. You have to check sensor sensor to see if they are bad, more than the entire TPS and the ISC and put the TPS, the electrician or mechanic does. And check the preservation of the pump or gas stack, it must be between 35lb psi up to 45 by much and when they accelerate it up 5 pounds.
Check that and the other is the distributor's time, the temperature sensor for heating even if you already explain the cylinder head.
Well that stode and I hope it contributes to something chao

First it is the first to stretch that all well -connected and clean earth cables are generating a good dough towards the block. Now the mazdas are characterized by relief problems, this is more minded, to dirt in the admission body Deves sacraral and clean it, and by the theme of heating, you must check that the theme of cylinder head as it monkey is correct or fall into the water, or water in the oil, or comprehensive comprehension in the water system, or water in the combustion characterized by white smoke in the escape. Now if the overheating is only in climbs you must check your thermostat Satch it and try the vehicle without it to see what it suspends.
