Ihave a missed firer

check the coil if coil is ok spark plug if there are ok may damage in emission valve or injectors code relate it to the problems are p0300 p0301 p0302 p0303 p0304 p0305 p0306 p0307 p0308

I would guess on a timing issue. Have you had any work done recently?

bummer,has to be the module underneath.
If the plug wires get bad it\'s really hard on the coil ,
May want to put a set on with the module,

Those bushes would have to be shredded or missing for it to make a knocking sound. And should be a visible problem, I would think.

if its still missing do a compression check. You could have a bad cylinder.

Hi, this may be a dirty injector. Try putting some injector cleaner in the gas tank to see if that will clear it up. If not, you may need to pull up the fuel rail and check the injector flow pattern.

make sure you have proper sealing washers under injectors,and you have only one washer in place ,ihave seen it happen before 2 washers will cause a loud knock if not that get injectors calibrated good luck

Not a good thing. More than likely it's the rod or main bearings.

lifters tick and noise is upper end of engine if lifters are making noise could be from a bad valve,bad lifter ,push rod ,oil pressure,rocker arm - need to take do compression test find out if valve problem and which cylinder is problem also take off valve cover and check for proper oiling of valve head and look to see if and are damaged or loose-------a knocking sound usually comes from lower end of engine,rod knock etc.and thats usually rebuild of engine

Check your rotor arm, distributor cap, HT leads and coil. The fault could lie with any one of the above.
