97 ford taures

[tkinney1991]

k plz somebody has to help i have a 97 taures gl and i have 2 ecm for it and i put the one in one code came up and i fixed it so the service engine light went off so im driving down the road and it goes around 35 and the car wants me to hit the windshsield, now with the other computer it drives fine but there are codes on that one i think 5 but the only thing is on that one the od works when it wants to like shift beautiful
i know im an idiot by switching computer but any ideas i really need it needs to get inspected

Wow, that's a difficult post to read and attempt to decipher.

Let's start by asking what caused you to get two more ECMs for the car, what was the original one doing?

It sounds like the ECM that is lighting the Check Engine Light (CEL) works better, so I'd suggest you consider that your baseline and work from there. Since you mention that it provided 5 codes, please list those codes, they could certainly provide some suggestions on what may be happening. It's possible one circuit/sensor could be causing all 5 codes.

If for some reason you decide you want to use the other ECM you're going to need to better describe what you mean by "the car wants me to hit the windshsield".

well when i bought the car it had a differnt ecm on it bc where the struct base is at they have the number for what ecm you have but i will go to autozone today and figure out what the codes are for u

[tkinney1991]

the one ecm i have with no codes the transmission feels weird driving down the road and when i get up to about 35 and either slightly get off the gas it downshifts really hard..........
but the other one doesnt just OD works when it wants to but shifts fine

Are both ECMs the same part number and the part number the car is supposed to have?

no they are not the one have with the 5 codes are an nzx1 and its supposed to be an nxz4

p0708,p0743,p1744,p0340,p1457

Since that PCM is not the correct calibration code for the car, it probably explains why the codes are all over the place. I don't find a definition for code P1457 for the 1997 model year. The P0708 identifies a Transmission Range Sensor open circuit. P0743 suggests a Torque Converter Clutch solenoid circuit failure, and the P1744 is applicable only for California cars and suggests excessive transmission slip has been detected. The P0340 identifies an issue with the Camshaft Position sensor circuit.

This PCM does not sound like it's compatible with your car.
