if that doesn't work you might look at the iac


Stick with your original plan. Find the problem, then fix it. That will save you money by not randomly buying parts and hoping the problem goes away. have the trouble codes read on your car. There will be information stored in your car's computer which will tell you what is wrong.


you can clean the iac and intake passage reset the iac also no code for iac
