    Hi i have the 1994 Mazda MX6. I find the problem. I put the car in time about 2 mouths ago and the CSP wires had been hitting the drive pullys and cut one of them. I put a new one on it and it is running great. Thanks for the help.

Check the gap between the prong and contact of the spark plugs. Your local parts store can look up the gap measurement and should have a gap tool you can buy for really cheap, sounds like that may be the issue.

If you downshifted into second at too high of a speed, you may have broken some major parts. I would get it checked by a professional who can properly assess the damage.

There is vibration in my mazda 626/ model 1992

Check the plugs for wear and replace as necessary. When you apply anything electrical, it naturally puts a greater load on the alternator and will require more power from the engine. 700-800 RPMs is about right but double check those plugs. Use NGK or Nippon Denso only. Let me know if you need anything else.

Try exchanging the MAP sensor from the other "good running" car. What I think you are experiencing is a flat MAP which fails to read more than the minimum. A MAP sensor out on these cars will make it run absolutely terrible and die as you have indicated.

By unplugging the TPS sensor you are effectively putting the car in "limp" mode. In this mode it ignores a potentially bad TPS, O2, and MAP sensors and or circuits.

Your 94 should be a 350 engine,is it?
That would be a timing chain,which means the distributor cap was removed to locate cylinder 1,
Your high rpm in neutral,and low rpm in gear sounds like a vacume leak,The turn signal problem I'm not sure because you didn't say if the battery is going dead or if it starts right back up.

Check the wires one at a time for oil on them when you remove them fron cylinder spark plug. If there is an excess of oil on them, they will short out to the housing under load and wii eventually kill the coil unit. They are not cheap, but if bad replace all at same time. Ford sells the wires and mazda. I would advise replacing the plugs with good plugs like ngk or denso. I will check again tomorrow to see if you need further help

The car is sputtering at high rpm

Hello, I would change the fuel filter especially if it's never been changed to your knowledge and if the car runs great up untill 4200rpms. If the filter is starting to plug then it will fell boggy and possibly jerky because the motor is being starved for fuel.
