No.
The TPS does not agree with the MAP sensor readings.
A little more info like engine and what ram and mileahe to start with would help.
Any other codes and what is it doing or not doing?
Then you will need a engine capable scanner to get and read out the map and tps readings and post them back to us.

engine is a 360.. 125000 miles.

it idles up and down up and down up and down...

it has trouble starting which i know could be something else but could also be related i would imagine
no other codes.

i only have a code reader. its an autoxray. i picked it up for 80 bucks.. i dont think it will map....

could i swap out the tps and hope it works??? or is this just me assuming just because the code is associated that it is a defective part???


thanks

Codes do not say replace parts.
But it is your money and time.
Or read my first post.
