Did it do this before the air filter replacement? This happened to me one before and it was caused by incorrect ignition timing. Yet a faulty Throttle Position Sensor, Mass Air Flow senosr or Manifold Absolute Pressure sensor can also be likely culprits. I wold look for a damaged or disconnected sensor near the air cleaner/intake.
B18c1 engine Took it in to a mechanic and they couldn't pinpoint the problem. Both oxygen sensors ok fuel pressure ok MAP ok Fuel filter replaced No vacuum leaks found with carb spray Valve clearances to spec Last time with a previous integra i had code P0172 and it turned out to be the injectors. Yet I only found that out by replacing them. With this integra I can hear them all clicking and they read around 12ohms, I hope its not injectors again.
Sounds like the factory alarm system is keeping you from starting the car. If thats the case your going to have to consult the owners manual or your local Kia dealer to help you figure out a way to bypass the alarm. On some factory alarms there is a programming or valet button that when held down after the ignition is set to position II or III will temporarily disable the system allowing for the car to turn on.
I would recommend cleaning out the IACV and FITV valves. Vacuum leaks specially can cause a surging idle yet I found in my Honda that cleaning out both of these valves solved the problem.
It could possibly be the cooling fan switch sensor, cooling fan engine, open wires between the fan relay and fan, or failing engine coolant temperature sensor. You can test the cooling fan engine by applying direct voltage via the relay location using a jumper wire. Remove the relay and with a piece of jumper wire connect both + and - ; if the fan does not turn on when the jumper wire closes the circuit you possibly have a bad cooling fan engine or an open/short in the wiring.
Check tire pressure. If its not tire pressure it may be misalignment of the front and back tires. Tire balancing can also be a factor in swerving while driving. Another possibility can be road conditions. And with extremely worn shocks/struts this can also happen.
Did you check your battery? If you get no light on your dash coming on then it sounds like an electrical issue. Check that your battery has correct voltage and that it is grounded correctly. Make sure the fittings are nice and tight and corrosion free. If battery is fine, i'd look into the fuse box.
This is somewhat vague. Does it beep when you turn your key to position II or III. Does it beep if you plug your seat belt in? The only time my car beeps is when I turn the car on and I don't plug my driver side seat belt in.
Where exactly did it solidify on the cap,inside the head or valve cover outside? If its on the cap or outside on the valve cover you might be able to use some engine degreaser. If oil has burned onto the cap or valve cover it will be harder to remove and might have to look at your local auto parts store and find a heavy duty engine cleaner. I used to soak greased up parts in a little bit of gasoline too but your have to me more careful when using gasoline as it can destroy seals and gaskets and of course ignite. Some people recommend break cleaner that leaves no residue yet I could not vouch for this.
From what I know the answer is no, I am assuming that you are speaking about an a/c compressor. Does the engine turn over? Timing chain/belt-if loose or broken the car will crank yet not start up. Failing fuel pump-no fuel delivery and no ignition Ignition coil/components-faulty coil or spark plugs can cause engine to not turn on Loss of compression- Faulty starter motor-car wont crank Battery-is it ok?, connected correctly? so many things can cause a car not to turn on, some newer cars have anti-theft systems that when activated/tampered can keep the car from turning on p.s. in a case where an engine uses one sole belt (crankshaft,p/s pump, a/c compressor, alternator) to run the engine and the compressor has completely seized up then it might keep the car from turning over yet I would find that to be unlikely.
