Stalls when driving?

I have a 93 Mazda Protege that to present has run great, when I started it yesterday it idled fine but when I put it into gear and gave it about 1500 RPM, it bogged down and stalled out on me. It started up fine, but then bogged down again and stalled out so I waited until today to try again. Same thing... There has been a lot of moisture in the air so I’m not sure if that could be a major factor, but figured it is significant. Also, the car revs fine in neutral. Please help if you can...

Try making sure that there are no air leaks in the air hose leading into the carborator. I had a similar problem and fixed it by wrapping the hose with duct tape. Works great now.

When driving car shifts in first& second gear but then hold light on dash flashes and remains in gear

1990 Mazda Protege mileage: 130,000. In the last few months, I have an engine stalling problem while driving at any speed. Without warning, the engine would stop responding to the gas pedal being pressed. The engine seems to sputter a little but otherwise no more responses. I would then have to bring the car to a stop, turn off the engine then start it again, and it would run just fine after that. This problem occurs at random intervals about one every few days to a week. I have maintained regular maintenance on the car and just recently changed plugs, distributor cap, rotor, and ignition wires. Also changed, oil, oil filter, and air filter. Could it be a faulty or dirty fuel injector? Does this problem have anything to do with the timing belt? I am about due for change of timing belt. If I continue running the vehicle despite this reoccurring problem, will it damage the engine? Please help, thank you very much.

The problem you are experiencing is probably caused by a faulty fuel pump. The timing belt has nothing to do with this problem, but if you are due to have it changed, it would be a good idea to do it at the same time.
