Just changed the timing belt, water pump, crank and cam seals...put everything back together and it's idling rough and hesitating upon acceleration. Checked timing mark with timing light and it's where it needs to be (15 BTDC) but light skips a beat from time to time and exhaust is not purring steadily but also skipping a beat as if it's on;y running on 3 cylinders (I replaced the spark plug in the one cylinder that I removed...also, broke the a/c belt tensioner so it has no a/c belt but that shouldn't make a difference

While looking for how to replace a Kia Rio crankshaft positionsensor, ... is on and i have a P0340 code, think this is theproblem? kia rio 2002.
I would suggest tat you have the valve timing professionally checked Pinging ( detonation) is from air/fuel mixture and ignition timing and the sound may be from incorrectly adjusted /aligned tensioner pulley on the cam belt.
Disconnect battery, remove breather box, disconnect wires to alternator. If it has coil packs, remove them. Remove valve cover. Remove power steering pump( don't unhook the hoses) lay it to the side. Loosen alternator. You may need to rent a special tool to remove crankshaft pulley. Unplug cam sensor, remove timing cover. remove #1 spark plug, turn crank by hand until you find TDC compression stroke (notice timing marks on cam and crank pulleys). loosen bolt on timing belt tensioner and remove timing belt. Remove cam pulley and replace cam seal, while you're at it you may as well change the crank seal too. Reinstall everything in reverse order.After you get it back together, you'll have to recode your radio, if it is equipped with anti theft. If you're lucky, this is about a 6 hour job.
It is really difficult to time these dbl overhead cam engines if you don't have the special tool. There is a fixture for holding the camshafts in place while the belt is being replaced but it is not cheap. It can be done but if you don't have the crank, both cams and the balance shaft all dead on perfect it is not going to run right. It sounds like you have one off a tooth. I did one on a Sonata recently and I found that everything moves when you apply the tension so I had to compensate the other direction the, amount of rotation caused by belt tensioner and had to do it several times to get it right.
Did you remember to reconnect your Cam Position Sensor after putting it all back together? One tooth off shouldn't have bent a valve (but pressure checking cylinder will answer that). Did you check TDC once the belt is tight?
water pump, take cover out and check if it is you must change thermostat check timing belt,idle,tensioner,crank seal and cam seal.that save you same money for later
check your oil make sure the crank seal is ok that u didnt spill ur oil and blow it up. then check the timing belt - you may not have had the tension tight enough on the timing belt and it may have skipped a bit causing it to not fire. i think thats the most likely.
