Hello every one
I have a 1995 mazda protoge 1.5L. When is cold in the morning or any time it runs good. After few milles driving start Hesitating when I accelrate the engine. This dosn't happen when the engine is cold. I replaced Mass Airflow sensor. Feul pump. Sparkplugs and wires. Feul filter.
any dody know what is wrong plese, any help will be very appreciative
Sounds like a bad O2 sensor giving the engine a lean condition when the computer go into open loop or it could be a bad computer temp sensor. It is located in the area of the T-stat and has two wires. The one with one wire is of the gauge.
