You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0102 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
* The MAF sensor may be faulty
* The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor.

Hope helps (remember rated this).

You have a vaccum leak. Look under your hood for a 1/4 inch black plastic line. It can be hooked into your filter intake housing. Usually this is where the leak is. There also is a black round plastic ball shape device under the hood. This usually has a vaccum line connected, you don't want any leaks there. Those are the easy fix suggestions for a vaccum leak. If you can't find it there, look for other vaccum operated items that are model specific. Hope that helps.

Blown or leaking head gasket, or cracked head...could also be leaking intake seals. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Is the engine getting fuel and spark?

Try to put a few teaspoons of gas in the throttle body to see if it starts up. If it doesn't then the engine's spark plugs may not getting spark.

A possible coil may be the root of the above problem.

If it does start and run for a few seconds then the spark is good, but the fuel pump may not be pressurizing (bad fuel pump) or the fuel injectors are not firing (possible PCM or Powertrain Control Module).

A crankshaft position sensor can also cause a no start condition.
It is located near the Crankshaft of the engine.

Here's more information about the crankshaft position sensor which if bad, can cause a no start or no run condition.
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition, the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms No Start / Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit. (See also Engine Mechanical)

These are just a few possibilities, and if one takes it to the dealer to have the engine diagnosed, that might be a good place to continue of the above doesn't isolate the problem sufficiently for repair of the no start condition.

It sounds as though you need to replace the gear linkage cable.

What you can do to diagnose this issue is - take an old spray bottle (some kind of house cleaning solution), clean it out really well (so nothing flammable is in it) and fill it with water. Then, pop the hood to your car, start the engine, and squirt different parts of your engine until you squirt an engine part that causes your car to shut off... then you know that's the problem part!
I had the same issue with my husband's car. We determined that it was the distributor cap, which we purchased at Auto Zone and replaced on our own for like $30.

adjustment causes that. Some vehicles have the brake always hot, normally, but opened by the brake light switch.

Yes but it is much easier to remove the drive assembly as one unit, there is more room to remove the transmission after the assembly is removes from the vehicle

look under car for adjustment in cable to rear-end.
could be time for a brake job.
lining worn down to point it needs to be replaced.

mixture or gas converter problem <replace gas switch or converter>

On most of your newer cars like yours the brake light switch is up next to the brake pedal. When the pedal is released, the switch is normally in the off position. It is a threaded switch to allow for adjustments and sometimes that is all that is wrong. I would check that first and if that is not the problem, the switch could be bad. Check it out before replacing it though. Good luck.

It might have something to do with your mass/air sensor located on the intake tube. Try cleaning the mass air sensor with the appropriate cleaner and also try cleaning the throttle body with carb cleaner.

Acc. squeek noise due to linkage issue, get it lubicated.

Regarding the clutch, you check the links, clutch plate springs condition. If there is wornout parts get it replaced. Gear shifting will be solved once you fix your clutch problems.

have the electricals checked. mostly the master switch.

bend the holder back into place

could be the crankshaft position sensor or throttle pos. sensor

go online - google your po code and you'll find answers. Just browse through all the links.

my 2000 elantra (2.0) had same prob., got a throttle position sensor (side of throttle body) from junk yard and fixed the prob. But yours could be diff. cuz it's a 98

the camshaft is the dot on the sprocket there is a small mark behind it on the cover 12 oclock the crank there is a mark on it look to the ten oclock number 1 tdc you will see the mark
