I recently installed the Airlift 3p and installed new studs all the way around, with school and clinicals I didn't drive my car for about a week and a half while everything was slowly installed. Yesterday I took my car for a drive, I turned the car on and the ABS light was on, as well as check engine and traction lights. I disconnected the battery for about 10 minutes but nothing changed. I took it for a drive and the brakes felt normal. I couldn't get above 4000 RPMS in first and second gear. Autozone pulled the codes and the only one showing was the ABS sensor.

Then as I was in the Walmart parking lot, I came to a stop and the car just shut off. It turned back on without any trouble. Today I started the car up after going to visit my mom and it had a little bit of trouble starting, but that might be because it sat in the cold weather for a bit.

Does anyone have any words of wisdom or advice here? I'm not a pro at this stuff and I'm at a loss here. I don't want to drive my car to school in fear it'll stall again.

first things first, the only area that anything you did interacts with the vehicle is the electrical system. i'd pull the air lift system fuses first, and then take it for another drive. it shouldn't affect anything, but is the easiest way to verify that before looking elsewhere.

did you and/or a buddy install the system, or did a shop? if it was a shop, bring it back and calmly explain the deal to come to a resolution to get the car worked on somewhere-- give them a chance first, but don't be a screamer... the next culprit is that something oem got knocked loose, or pinched during the air lift installation.

and the last culprit is that it has nothing to do with the air lift system, and it's something else entirely.

@Kaily an ABS sensor code will throw the car in limp mode. Also might try to stall under braking. Happened to me when I had a broken abs sensor for a week, car barely wants to run under that condition.

Almost makes me think carrying a spare ABS sensor for any wheel job might be a good idea.

While 500 is a bit low, 1000 - 2500 RPM on a wamed up car at idle is not normal either.
Normal is 650 to 800 I believe, depending on AC

Thank you for the advice, we tapped into the windshield wiper fuse for the airlift system. To be honest that's been randomly acting up too, the wipers come on at random and I can't do anything to turn them off..

A couple of friends helped install the system since I didn't know anything about how to install it and they've installed it a few times on cars they've had.

I'll take another look at everything this weekend.

this is seriously very concerning. and why the windshield wiper fuse, of all the fuses to pick from?!? a proper install of any device shouldn't result in electrical issues.

*my internal voice is now screaming at me to RUN AWAY, RUN AWAY VERY FAST AND DON'T LOOK BACK*

So to speak to the 500 rpm, my WRX had similar symptoms when I did my exhaust, intake, and EBCS. I was surprised to learn how much the MAF sensor was tied to ABS, TCS (wheel speed sensor). Although I agree that your wiring to the wiper fuse is puzzling, maybe clean your MAF sensor with some MAF cleaner. But maybe your car went to limp mode because of the questionable wiring. This is why I'm a mechanical guy, I despise electrics lol.

duct tape is conductive, baling wire has a high resistance, and wd40 is flammable. none of those things should be mixed with electricity...

:offtopic:(<-- damn dude, smile a little) The aluminum stuff used to seal the seams on duct work is without question conductive. General purpose duct tape is not conductive, but it is also not insulated (doesn't protect against getting zapped). It's just not advisable to use because it offers minimal fire protection under a load.
