I have a 95 mercury tracer 1.9, I fixed the chugging on acceleration problem, now after driving for a bit it will make a popping sound then check engine light will come on and lose power for a bit then will go back to driving fine, can someone tell me what it is.

I would suspect a vacuum leak or air intake leak somewhere, like at the intake manifold or the air tube.

What did you do to fix "chugging on acceleration"?
i have exactly the same car with almost the same problem, my car does not pop thank god! But it does chug and sputter while i am at a stop and then when i accelerate from that stop. And after changing the spark plugs, fuel filter, oil, oil filter, transmission fluid, air filter and houseing, and the brake booster i am still having problems. i believe it is the air intake manafold gasket that is the probelm.
