My 2006 Chevy Aveo revs up the RPM's upon start up and eventually goes back to normal. Recently it has not been responding well when taking off from 1st gear and wants to stall out sometimes. I backed out of the driveway and put into neutral and the RPM's started to bounce up and down for about 15 seconds and slowly went to normal. Please advise what this may be and how to fix it.
What engine does it have ? Could have come with 5 different ones . If it has the 1.6 L engine . has electronic throttle control.
The throttle actuator control (TAC) system is used to improve emissions, fuel economy, and driveability. The TAC system eliminates the mechanical link between the accelerator pedal and the throttle plate. The TAC system eliminates the need for a cruise control module and idle air control motor. The following is a list of TAC system components:
• The accelerator pedal assembly includes the following components:
- The accelerator pedal
- The accelerator pedal position (APP) sensor 1
- The APP sensor 2
• The throttle body assembly includes the following components:
- The throttle position (TP) sensor 1
- The TP sensor 2
- The throttle actuator motor
- The throttle plate
• The engine control module (ECM

Check your fuel pump presure. Pump is in the tank. Also try and loosen the fuel cap, the tank vent may be stopped up.
SOURCE: Will not read codes from the OBD connector
Yes the OBD Connector is fused. The fuse is a 15 AMP mini and located in the Fuse block on the Left hand end of the Instrument Panel requiring the Drivers Door to be opened for access. The fuse is located near the bottom of the Fuse Panel. It probably also feeds the Cigar Lighter circuit.
Testimonial: "It was the cigar lighter fuse.Strange that it ties in with the OBD, but it fixed the problem. Thank you for the advice."

check the air bag fuse and also make sure all of the air bog sensors are working properly
SOURCE: idler is too high on start-up, goes up to 2.5-3
I bought my 2004 aveo 49 miles. I've had several issues with the car. But recently I been experiencung high idle at start up and clutching. I change IAC. Plugs and wireds. Nothing worked. Today the high idle became constant. It was a metal bubble flex tube near the IAC unit that goes to the exhaust stuff down behind the motor. It apparently was cracked cause today it broke causing the constant high idle sound like a vacumn. We blocked it off with a stick to get the idle back down to 900 rpm instead of 3-4000 rpm took we can get to auto zone for high temp hose per Chevy dealer. I hope this helps someone cause it was fustrating and costly.
This is a picture of your throttle position sensor. It is located on the throttle body, where the air inlet tube enters the intake manifold. Simply unplug the wires, remove the bolts holding it in place, and replace it with the new unit. Hope this helps!
