my 96 cobra was running fine. changed my rear brakes and removed old battery. the engine was nasty so i lightly rinsed the dust off! and let it set. the battery was not in the car during the rinse. changed the stock air filter to a K&N and removed part of the air box so it would breathe better. took my air hose and lightly went over damp areas on the engine around the heads. then i hooked up the new battery. cranked the car it started right away! for 1or 2 seconds shut off. now it cranks slow like its struggling to crank. it dont sound right. like its under pressure! can anyone tell me where to start first! thanks don
