ok guys on top of the sputtering an poping now i am ideling at like 1300 instead of my normal 900 an it feels like i am not shifting into overdrive.... I think I need to flush my tranny for that but i had error code po135 pop up cleared it an it hasnt come back yet do you think i got a bad upper o2 sensor... an ill also be doing a full overhaul on it... oil, oil filter, air filter, tranny flush, collent flush, plugs, wires, cap, an rotor...... anything else you guys think i should do

Check your fuel pressure and idle stepper motor.

blkcherokee

what is the idle stepper motor an where is it located

fantic238

The IAC is located on the throttle body near to the tps and regulates the idle speed.

blkcherokee

would it through up a error code thoe

fantic238

No, but the idle at 1300 means two things: iac malfunctioning or lean mix due to low fuel press or bad O2 sensor.

blkcherokee

so when i go to the store i am asking for the idle stepper motor or what

blkcherokee

anyone any other sugestions on what this could be

I had something like this happen to me as well. Not saying the "Same" thing. But similar sounding. I was always getting a 3rd cyl misfire. I changed out O2 sensor and air filter. Which ever one it was, it fixed it.
