SOURCE: ENGINE WONT TURN OVER
sounds like the timing belt it has a interference engine so if the timing belt broke you could have bent rods and cracked pistons or worse. good luck
SOURCE: Codes P0303, P0451,P0440- gas cap replaced 2X check engine light
PO303 # 3 cylinder miss fire: check ign coil and wires,
PO451
PO440: looks like perhaps something to do with the fuel line change! i would look further into it before traveling far perhaps a really well reputed garage can help?????
SOURCE: My Kia Rio stalles while in drive and reverse.
If it runs, and you can throttle it up in park, it's not a fuel filter. You need to know what it looses when it dies, fuel or spark.
SOURCE: engine misfire from 1 & 4 changed spark
Did you use the right plugs?
Pull them all out, inspec, them for phisical damage.
Son put theplug for the 2.4 instead of the plugs for the 2.2 in his cavalier and he only clipped one with a piston (Missfire)
Do you have the fireing order correct?
SOURCE: it violently shakes when parked or when stopped
If it shakes, it is normally either a bad motor mount (if the car runs fine) or your car is "missing" on one or more cylinders (misfire). The belt will squeal because they stretch with use. That can be solved by replacing the belt or tightening the belt. The squealing sound won't go away until you do one of those two things and is unrelated to the shaking. You PROBABLY are experiencing a very "rough idle" if any of the hoses to the intake (top of the motor) have a hole or crack in them from heat or age. This is common and is the first thing to look for to avoid high repair bills. Bad (worn out) spark plugs or old cracked plug wires can also cause a misfire. You could also have a bad coil pack, but mine has gone 186,000 miles without coil replacement or new plugs or wires and I've only changed the fuel filter once. Another possiblity is a faulty Idle Position Sensor that is not properly regulating the fuel delivery. Normally that would cause an engine light to come on also though and you can have someone at the parts store "read the code" once the engine light comes on.
Testimonial: "good feed back"
