Default Random misfire

i have a 2006 suzuki forenza with codes P0304 P0300 P0301 P0302 P0303 AND P0314
The Check engine light is flashing and the car is running extremely rough. It all started when I was driving home and heard a tapping noise when accelerating so I accelerated a little more and then the car started misfiring and the CEL started flashing. I changed the Spark Plugs, Wires, and Coil pack with no success. Any help would be great. The car also developed a coolant leak near the center of the engine towards the windshield.

Hi Tylergg19
Can’t really diagnose a car over the Internet but you definitely have a problem. Ok first of all the coolant leak on the back side of the engine. There is a coolant hose that runs along the back side of the engine, a couple actually. One of the lines likes to brake. I’d start with that. There is a line that runs from the head to the throttle body, this keeps the butterfly valve from freezing. Then there is a line that runs to the coolant reserve tank. You need to check these for leaks, replace as needed fill coolant. Now tapping, much harder to tell. Check your oil see if it’s low at all. It seems all your codes are related to a misfire either general or related to a specific cylinder. This is were things get a little harder. Remove your oil cap is there any milky residue on it? Does it smell like gas at all? This is just a simple test to make sure your head gaskets ok. No milkyness or gas smell? Ok! Now this code p0302. it means that the “Misfire Monitor has detected more than a 2 percent variance in RPM between the firing of any two (or more) cylinders in the firing order.” This would lead me to believe timing. Now there’s bad news and not so bad news lol. The knocking, the misfire and timing codes could mean your timing belt either broke or somethings wrong with it. Here’s the bad news. This car has an interference engine basically what they s means is it runs under very tight tolerances. If there’s a problem with your timing belt the pistons could come into contact with your valves possibly bending a valve causing a tapping noise. You could remove the little clips and pull forward the top of the timing cover to see if your belt is ok. This needs to be checked by a mechanic as well. Now the not so bad news is this, your cam sensor could have gone bad. This could cause your timing to be off causing a misfire. See not so bad. Now the warning. DO NOT DRIVE THE CAR UNTIL YOU KNOW YOUR TIMING BELT IS OK. The reason? If something is wrong you’ll make the whole thing worse. So check out those that bugs and report back. If your not sure tow it to a mechanic and have it looked at. Any news ther question just ask
