Hi this is my firts time to post. And i have bad news.

have a 97 v6 and it starts up just fine but once i try to drive it it starts stumbling but after about 2,000 rpm it starts to run more smoothly i think its some problem whit the Some Sensor 02. The problem born becouse i wash the motor whit one spray and after wash whit water. I change the coils circuit, and clean the Spark plug wires, and go to the Scan and this appear the code to TPS , clean an calibrate and nothing, do you think my problem is to the O2, or another issue in relationship whit the water. Thanks and sorry for my Grammar i am not American, and my primary lenguaje not is the English is the spanish.

 

No, no, no.

You checked the code and the TPS system came up. Please check through it thoroughly. Check for the proper voltage. That shot of water may have damage the TPS.

There is almost no reason to replace an O2 sensor when it is not the cause of the problem and the code scan says that as well.

 

AlfredB18 : In fact i buying a new TPS sensor. and have the same problem. Today i am remove all Spark plug and spark plug wire. I have one wire borken only the jacket not all wire, may be this is the problem i am change and test the car, but sincerly i dont mine this is the real problem. The TPS i am sure is not a issue, do you think in another sensor maybe MAF, or EGR( i am not sure is this the correct name) , i am tired but i try , and try and try. thanks men
