1995 mazda, stumbles upon acceleration
|
|
|
i have a 1995 mazda 626 2.5L, 5sdp. it hesitates/stumbles upon acceleration until 1600 - 2000 rpm then runs ok. replaced plugs, dist cap, rotor appears ok. wires resitance under 11k ohms/3ft. new fuel pump/strainer/filter. 2 stage injector service(manifold and fuel additive) also tried a known working MAF meter. any ideas?

Check engine light on? You try a coil output test. Good coil should be able to produce a spark that jumps 3/4 of an inch.

Pull the distributor cap off and you'll see the coil lead. Take a 12 volt test lamp connected to battery ground. Hold the probe of the test lamp against the coil lead while someone cranks the engine. Pull the probe away from the lead and see how far the spark can jump to your test lamp while the engine is cranking. Should be able to jump 3/4 inch gap with no problem. Don't crank the engine with the cap off without something for the spark to jump to though.
