Question about 1992 Mazda 626

Engine problem - 1992 Mazda 626 (V6)

My Mazda 626 had done about 220,000 k's. When the car has warmed up, and under load or I try to accelerate quickly, the engine seems to rapidly loose power (almost like it is changing gears) + puff and splatters. It has now also started to overheat under load. I presume it needs an engine rebuild? I have a reasonable understanding of cars and worked on them back in my early days, so is there a step by step manual (I can purchase) to repair this? If so, how much do you think this will cost + what would you estimate the parts to costs?

Yes you can purchase a repair manual online if you like from this site, or local parts stores they run about $25.00 or so, and might consider either purchasing a OBDI diagnositc scanner or take it to a shop to save guess work. You can perform several tests to check properly such as compression test wet and dry or simple spark test, fuel pressure test and so forth all of the tests can be found in repair manual.

Mazda 626 92 v6- engine sputters when revved over 4000rpm and cuts out completly for about 2 seconds when you turn left a bit too fast

Sounds like fuel starvation. You don't say if it is carb or injectors, but sounds like carb. Check the fuel filter, the float level and needle and seat and the main jets for partial blockage. Yu can also check the fuel pump delivery and pressure and the vapour separator.

Under steady acceleration, engine light goes on

Being a 95 it dosent have OBD2 so it may not store a trouble code in the computer.
From the symptoms it sounds like either, Air flow sensor, O2 sensor
The O2 will not usually cause stalling under acceleration.
