Thx destey, I did not remove the throttle position sensor. I will give your suggestion a try tho.

Yes, it is. The new one came with a new o ring already in position for use.

hi everyone. I'm looking for help with the idle air control valve on my car. I've been procrastinating replacing the IAC for about 18mos. My mechanic has cleaned it and it improved for about a year. Since this seems to be a straightforward repair, I decided to buy a new IAC and replace it myself. Two screws and clip, what could go wrong? I was able to find a new genuine Soob IAC for under $320. Upon installing it the engine has raced and sputtered. When stopped during the test drive, the engine would rev to 4k rpm and then drop to 2.5k rpm for a few seconds before racing back to 4k. It did this several times. It also would jerk when I let my foot off the accelerator the way u would expect when driving in the top of a gear. It is a 5spd trans, but I wasn't trying to strain the engine in anyway. Do I need to put the original part back on? With the original part my car idles rough, the engine might race (2.5k rpm) for a few moments upon starting, but then it calms down closer to 1k rpm. When driving with the original IAC I'm experiencing stalled engine when I stop or it barely maintains a too low idle. Please help if you can. I really need my car working well again. And I'm broke which is why I'm not in a shop with it for this issue. I needed this repair to be a simple plug and play and it's just not like that at the moment. I've owned this car for 10yrs and need to get a few more out of it if I can. Thanks in advance
