Hello! Welcome to justanswer!
Is the chain on like in the diagram below?
Ok, so they are exactly as in this picture?
yes. Do i need to align my timing marks on a specific cylinder? Because cam had spun around. Or just any way i can get them to align is right.
If the markes did not line up when you pulled the timming cover off, you have to spin the cam and crank seperatly so the marks line up with each other. If youhave the markes lined up correctly, then you need to make sure the plug wires are on corectly. If you need a diagram to show you what wire goes where i can post it for you.
Here is the diagram.
Okay so if i hook up the wires from coils No.1 should go to No.1 cylinder as the same with the rest correct?
As long as the wires are in the correct location according to the diagram, it does not mattery what coil is there " if they where put in the wrong location they will still work the numbers on them is just to make it easy to know what wire goes where". So if the coils where put in backwards you woudl conect plug wire number 1 to the coil post marked 2 ext. Or the best thing to do is swap the coils so they are in the correct location.
yes the numbers on the coils will coinsides with the spark plugs location to each cylinder. If the coils are in the correct location, and you still have a miss, then you need to do a compression test on all 4 cylinders to see what is going on. Please post the test results for each cylinder so i can see what is going on.
Yes even if you accept my answer I will still work with you till this problem is solved.
And yes if you have low compression then the code p0300 will set.
You are very welcome.
$250.00 is way to high. The machine shop near me that i use only charges me $125.00 to clen pressure test, serface, and a 3 angle valve job. See if yu can find a better machine shop.
If you can see a crack then vacuum can leak down that crake and cause you trouble. The best thing to do woudl be to grind the crack out just a little and use jb weld to fill the crack back in, and then use a file to smoth it back down flush with the mating surface. this will insure that the intake does not have unregulated air going into the engine.
Make sure that what you see is a crack and not a scratch. there may also be casting flaws that will look like a crack, but realy are not.
Let me know what you find, and what cylinders are filling with fuel.
