Question about 2003 Hyundai Tiburon

2 Answers

High fast idle at start up.

2003 v6 tiburon idles at 2000rpm for first few seconds when cold. If you turn the air on and off it goes down right away. But still the fast idle is high just a few seconds when you have no oil pressure. This is hard on the motor. Bought the car new and it did not do it when I first got it. The dealer says it is normal. I don't believe it. Does anyone know what sensor controls this? Thanks!

    03 Tiburon has a fast idle (5K) on cold start up. Afraid to let it keep running at that speed especially in cold weather

On most newer cars there is a fast idle motor controlled by the computer that will hold the fast idle till the engine reaches a preset temp in the computer then the engine should drop down to the set idle according to specs for that car. If the oil pressure continues to stay low after the idle goes down you may need to replace the oil pressure sending unit or if worse case the oil pump.

True. It's not unusual for a car to idle high when you start up as lnog as it doesn't stay high you are ok. However, if it was idling too low that would be bad.

    In regards to the person who has the same problem, idling at 5,000 rpm on start is too high. You may want to get that checked out if you haven't already.

It likely has EFI (electronic fuel injection) and an idle air control valve that regulate idle speed. They can get gummed and fail to have a fast idle when cold, or get stuck the other way, and have a too fast idle all the or regularly take its time slowing down after you take your foot off the gas. An engine temp sensor can also cause a lingering high idle if it reports the engine as still being cold after warm up.

When I start the car it stays at 2000rpm for a few moments then drops down. I'll drive for a few minutes then put it in park and it revs up and down.

I have a 04 mustang 3.9 v6 and every time I start it, its rev a little high and makes a loud ticking noise but after a few seconds it idols down and the ticking goes away why is that?


Fords do rev high when first started but a breather filter may be dirty,the ticking is probably the valves that haven't gotten oil pressure to them.If it has high miles you may want to use a full synthetic with your next oil change so the valves will be safer from start up wear.I personally use Slik 50 and Quaker State Synthetic Blend...

I have a 94' Isuzu rodeo with a fast tap


alot of the 4clys had ajustable tappets that might need adjusting
V6 have tappets adjusted also but are shims on top of bucket over valve spring, this is hard to do as you may need to change shims to get correct valve clearances suggest dealer to do.
if the noise comes in and out while maintaining 1500-2000rpm when stationary it is possibly worn valve guides which is common on high km vehicle.(head repairs)

My 98 honda civic lx (automatic) idles high around 2000rpm when the engine is cold and when is hot idle goes up and down. I recently changed distributor, distributor cap and rotor. No engine light. When...


with your a/c issue, the compressor might be faulty and not engaging and disengaging. have the a/c system level checked and recharged if necessary...if okay, then start to check the clutch in the compressor to see if it kicking it or not...maybe the low side or high side switch...as for your idle, it really didn't sound like a distributor,.....to me it sounds like you have a faulty, Idle Air Control Motor in the throttle body allowing in too little air, and when a/c is on, its just right...have them both checked,

It kills when you remove your foot from the accelator fast


Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
