Engine Performance problem
1998 Ford Escort 4 cyl Front Wheel Drive Automatic 125526 miles
I have a 1998 Ford Escort SE Sport with an automatic transmission, actually my problem is that the vehicle is not left on at low rpm and when accelerating revolutions do not rise and remains flooded, does not exceed 2000 rpm with throttle and repeatedly stepping on the accelerator the engine revolutions rises to a good acceleration, but when I release the throttle is off, on many occasions when in 2000 rpm and being drowned by releasing the accelerator up about 500 rpm more and back down, also to leave the throttle in the background just accelerates and decelerates between 2000 and 3000 rpm, remember the pedal to the bottom. I changed the O2 (Oxygen Sensor) TPS (Throttle Position Sensor), the fuel filter and spark plugs and the problem continues, also found a broken hose running from the intake manifold to (Canister Purge Valve) does not as desirlo in Spanish, this hose is changed too. At other times the acceleration to achieve good, I have for several times the acceleration from 2000 to 5500 rpm about four to five times and when you release the throttle the engine remains stable at low 800 rpm +/-, turn on the A/C at maximum lights and remains on, this only when I take the rpm to the maximum for several times, but turn off the engine and turning on the power again the same problem continued acceleration and drowning. Please someone help me with this.
Thanks in advance.
