Long story short On friday i hydriolocked my car, i couldnt see the road, was 2 minutes from home and car died, opened the door and turned out i was in knee deep water. My pod filter was completely submerged so it was an easy diagnosis. I however made the mistake of trying to restart my car once while in the water and once when i pushed it out. Anyway i delt with the car 2 days later, dried the fusebox, and it started, took it home, left it running till all the smoke drained outa the exhaust, changed oil, oil filter, converted back to stock intake, new filter and now the car run AMAZING. It is pulls harder than ever before which has stumped me completely and its not by a little.
my question is, how is my car sudenly faster after i hydrolock it and ditch my CAI.
however im having idle problems, it idles at 500 revs and the car shudders like crazy while idling, feels like it will stall (its an auto tho), i also have a rattling sound which i think is comming from my exhaust. Any ideas as too why this is happening?
i shall aslo book a compression test too c if ive warped any rods.. .etc.
