20 Most Recent Hyundai Motor 2004 Sonata - Page 6 Questions & Answers

I'll put my bets on a faulty gage...but that's just me.

There's like an upper intake (Hyundai calls it a surge tank) and the lower main intake. Are you needing to remove the main one or just the upper intake. In any case there are a number of steps to do and quite a bit if I were to post it on here. If you would like, feel free to email me directly at [email protected] with all your information. I will be happy to make up a PDF with step by step instruction with pictures and email it back to you. No there won't be a cost for it....

It could be your timing belt. You better have it checked out because you can do serious damage to the engine by turning it over if that is the problem

O2 sensors just plug in.

no easy way, yopu will need a air impact 1/2" drive. Unles you can get to the flywheel and jam it, or even take the starter out and jam it. with a pry bar or something.

I'm assuming you have good fuel pressure. Do you have spark to the plugs and normal compression ?

Are you saying you don't have any fuel pressure at the injectors ?Is the pump getting power from the relay ?

The actual speedo head in dash. Try to disconnect battery for 30 mins. Can reset unit , make sure you have radio code fist.

I just bought a 2011 Sonata and am experiencing the same problem. Going downhill with cruise set at 55 mph; speed increased to 70 mph and was still accelerating (from the downhilll grade) when I finally pressed on the brake.
This is not normal. My Honda Accord never varied from the cruise setting by more than 3 or 4 mph ... going uphill or downhill.

If appear this problem... May be a smart chip in the middle of the engine failure... Lead to problems without blocking variable speed... Or the engine gear.hope help you-auto diagnostic tool

BOTTOM OF THE CRANK CASE BY OR BEHIND CRANK PULLY

THE PROBLEM IS YOUR AIRBAG MODULE (computer) it is pretty expensive to fix since it needs to be replaced. Around $500 prolly more unless you know someone. Airbags won't go off randomly. But they prolly won't work when they are supposed to.

going down steep hills will all but over ride a cruise control, since the motor is trying to keep the vehicle slowed to what your desired speed that you set , unfortunately this doesn't always work,, as your speed increases, the motor can't keep the speed reduced, when you apply the brakes, the system shuts off, cruise controls were meant to be used pretty much on long flat surfaces with Low inclines ,,
