A plugged or partially plugged EGR valve could cause that.
timing could be off, or youre distribitor cap and rotor needs to be changed out, plugged fuel filter.
Replace the ignition coil.
Plugs, Wires, Cap, Rotor, the ignition coil, Air Filter, Fuel Filter
Run a compression test.
Plugs, wires, cap, rotor, air filter, pcv valve.
if it has spark plugs check the distributor cap and/or rotor button for corrosion
check spark plugs, plug leads, distributer cap and rotor button
It is a triple rotor Rotary engine. A b2000 was there pickup.
try changing your oxygen sensor I have changed the oxygen sensor and it did not help. Do you have any other ideas? Could it be the carb?
rebuild or replace.....you have a serious issue there
For a 1998 Mazda 626 the minimum thickness is .866 inches for the front rotor and .315 inches for the rear rotor. This is the same for the 4 and 6 cylinder versions.
It could very well be a stopped fuel filter. Follow the fuel line from the engine to the tank to find it. I have the same problem.. replaced fuel filter, replaced dizzy cap, rotor button, ignition leads.. (all 10 of them.).. turns out my problem was the mechanic put leads 1 - 2 backwards when he replaced the rotor button. Also, the screw in my rotor button would come loose, dont know if this is a common problem... but a bit of 'plumbers tape' solved it. :)

Inside the distriburator after you remove the rotor button.
1-3-4-2 Rotor turns clockwise.
you need cap, rotor, plug wires, air filter, plugs, fuel filter, oil, oil filter, and fuel filter.
Just take a hammer and bang on it while spinning the rotor. Keep going until if gives.
check the rotor botton in the dizzy
It can be changed by either reversing field winding connection or rotor winding connection.
Check to see if it getting spark/fuel Check rotor
try changing your fuel filter.
Check to see whats missing when it won't start. Needs fuel & gas to run.
