Hey guys,
My idle was being a little funky on my ap2 (04) and idling around 1300-1500 warm so I cleaned out the iac valve and the idle returned back to normal. However, I noticed when the engine is spinning down after I put in neutral and the idle is dropping to idle at around 1-2k the idle raises 1-3 bars for a second or less before settling at the normal idle range. Is this normal? I didn't really notice it before when driving. Has anyone dealt with this issue? Should I try resetting the ecu? It doesn't do it all the time but enough to annoy me. Open to any suggestions. Thanks!!

 

It's somewhat normal for it to bog down a bit and then come back up to the targeted idle speed after many miles/years have passed but I noticed that mine doesn't do it anymore post DIY injector cleaning. That also produced better on road performance and smoother idle so I highly recommend you give that a try. You could reset the ECU now if you want to rule it out but I'm pretty sure the injectors need a good clean regardless.

 

thanks so much for reply dude! its not really bogging its just raising a couple bars for a split second before idling normally so its super weird! I'll try resetting ecu and if not Ill try cleaning the fuel injectors. Car has less than 60k miles so its a little strange haha. Thank u again

 

You're welcome. Hope it works out
