I need to replace the ignition coil on my 2001 tiburon. will the timing need to be adjusted after changing it

a crank sensor will make you not get a signal to trigger the power for the coil so that may be the problem with it. If all else is ok, is the check engine light on to scan it for the crank sensor code.

More than likely its a faulty coil.

i had the same problem with my moms 90 sentra... it turned that it could of been either ignition coil or pickup coil.. if ignition coil is good then possiby it could be pickup

A mechanic would check to see if the coil had voltage and a ground signal.

Pull a spark plug and see if it is wet with fuel. If it is than I would suspect a bad crank sensor. Very common on hyundais's. I need to know what engine you have to post specifics. Most likely the crank sensor is located down by the crank pulley behind the timing cover on the four cylinders. The timing belt needs to be removed in order to replace the sensor.

Sounds like a clogged exhaust converter,unless the
problem just started & got worse over the last two weeks

A completely dirty gas filter, would seen unlikely, as over the
years, repair shops change gas fiters,ignition wires & all sorts
of things, over & over just to sell something you don't need

A complete failure of almost every ignition coil all at on time,
which I experienced last sept,or a failed ignition module if you
have that

That leave you checking fuel pressure with a gauge attachedon a road trip & a scan tool would be nice also,to look a pressure & fuel trim

You need to test the TPS Sensor as well

I away I hope these issues are not the result of just neglected
preventative maintenance on your part

Only my opinion but that is 80% of all vehicle issues
Drive it till it breaks,so to speak

Check ignition coil pack for spark, at ignition coil with engine running disconnect one spark plug wire at a time, they should all spark, if no spark out of any of the coil pack, replace coil pack.

I would check the connectors on the coil packs, spark plugs and wires and replace them if they at all seem worn or tired. My 2000 sportage ran rough so I replaced the fuel filter, coil packs, spark plugs and wires, cleaned out the IAC valve, TPS, throttle body and intake tube, tightened the screws on the fuel pump access door under the right rear seat and cleaned the ground wire and the contact surface and I added 1 ground wire from the block to the firewall and 1 from the valve cover to the firewall. Your timing is more than likely right where it needs to be but the ignition may be slightly missing from a bad coil pack, dirty or fouled plugs or a bad plug wire.

tiburon uses hydrolic lash adjusters there are no valve lash adjusting If you hearing a pecking sound on the top of the mtr try some oil additive or replace the hydrolic lash adjusters

Based on what you've described so far, you are not familiar with the system you are trying to repair (not intended to insult you). Take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.).
