I did a few mods to my Galant about a month ago and ever since then, the car will not idle properly. It will idle just over 1k rpms, it will idle sub 500rps, it will act like its about to stall then shoot up to 1k+ rpms. Sometimes it will just stall out, and sometimes(rarely) it will idle at 750-850rpms. Most of the time its surging I guess, dropping and going back up, if graphed it would probably fit a sine wave quite nicely. If I let it surge for 15-30 seconds it will just stall.
Before I did the mods, the car would idle flawlessy, I would always make fun of my dsm friends that had poor idles because mine was so perfect 100% of the time. The only mod that I did that I could possibly associate with ruining my idle would be installing a 1g intake pipe, cutting the filter canister off, and removing a little cylindrical filter thing from the MAS right where it connects to the intake pipe. My battery is currently where the stock filter housing was.
I have a list of things I have tried to solve this issue over the past month(draining my college student wallet), nothing has seemed to fix the issue. If you would like to know what I have tried and the mods I did, I will post them, just didn't want my initial post too large becuase then people don't tend to help/reply. Prior to doing any mods, my only problem with the car and still is a problem is maxed fuel trims.
So my question is if there is anything else that I should check that could have messed with my idle when I changed the intake location. The MAS plug is not being pulled, but is reaching as far as it can to remain plugged in at the new spot. Oh and I didn't check for any errors until about a week ago and I noticed that I had "12: Airflow Sensor." I reset the ecu and it took a week for the error to pop up again. Thanks
