Hello everyone, I've tried cleaning the solenoids, and they were a bit clogged, but it hasn't fixed the error and my lacrosse runs a bit poorly stuttering. I feel like they could have failed, but I'm not sure how to check. Assuming they're fine it's a failed censor, then. Any tips for determining if a sensor has failed, or not? Update: bought and installed a new intake solenoid. Fired it up and it ran like a watch, again. And then the check engine light turned off after I put some gas in a half mile down the road. Thank you!
