Question about 1987 Mazda 323 4-Door
Car recently had tune up. Idling beat is not uniform and there is indication that it may cut off but does not. No matter how long the engine is kept idling and the car is in reverse it will cut off. If I give it sudden gas or if I take my foot off the gas pedal it cuts off in reverse. Going forward the car will shake, buck and cut off. Turning the ignition will start the engine promptly.
Once car begins to work properly after the above, it continues to accelerate and only when I am slowing down or come to a stop light it threatens to do the above.
The top part of the carburator was sprayed. The module in the distributor was changed. My mechanic says that the only thing left is to clean the gas tank which to my knowledge has never been cleaned. Car is mazda 323 1987 model, 4-door sedan
How many miles on this car? providing the choke is all the way open at operating temps and the engine is still not smooth and the tune-up parts are new, i would search for a vacuum leak somewhere on the intake manifold and carb. using carb cleaner with engine running spray around intake and lower carb if idle changes, you have found a leak. make sure the choke is working properly!! dirty fuel tank is possible but not likely, with a tune-up i would assume the fuel filter was changed. was it dirty? was the timing checked? does car run well at speed driving down the road?
