So I washed my engine bay today with some Zep degreaser. Everything looks great, but now i have issues.
I wrapped up the fuse box and the alternator to keep the water out. I lightly soaked the engine, soaped up and then rinsed it off. Didn't use any high pressure or anything like that. I let the engine dry for about 3 hours while doing a oil change and some other stuff. Before letting it air dry, i dried it pretty well with a leaf blower which worked great.
Just took the car for a spin and it seemed slower than usual. I have stage 2 APR, and it seemed slow and sluggish. I pulled over, and checked to make sure the tune was on, then got a CEL. Drove home and it was still slow and got in the driveway and the car stalled out. The ESP light was on briefly as well.
I removed the coil packs and there was a little condensation which i removed. Possibly the MAF? Plugs look like they have white chalky stuff on them, especially the far right cylinder. Overheating??
