Question about 2005 Hyundai Sonata

1 Answer

Late 2005 Hyundai Sonata 6 cyl. is haveing a huge power loss when you step on the gas lightly and is getting worse by the day, by more speed it messes up. We replaced all the spark plugs, crankshaft position senser, and took it to a Hyundai dealership specialist and he replaced one of the fuel enjector wires. Now it is running worce. We noticed when we replaced the spark plugs that the three spark plugs in the back (under the manifold) were burnt out way worce than the three in the front. We were thinking that someone just replaced three in the front and were to lazy to do the three in the back but there is also a chance of something being wrong with the three in the back as well. The main problem is speeds between 25 and 40 mph. But now after we put all of what I said before in, it is now messing up on all speeds. You gun the car and it cuts out, but dosn't stall out compleately.

My Hyundai Sonata GLS, with 2.5 Liter 6 cyl.

You cannot, First thing you need to do is get the codes using a diagnostic scanner that is able to access the airbag module. Your basic code reader will not do this. The code will tell you what airbag has an issue. If your a smoker in the car most likley the ASH destroyed the clockspring under the steeing wheel.

Transmition problem

It might not be the transmission. IF your needle is dropping that rapidly, more than likely you need to have your speedometer inspected UNLESS you feel your car **** and rapidly slow down from 100km to 80km. Then it's quite possibly a transmission issue.

IF you step on the gas, and you just feel the normal light push from stepping on the accelerator pedal and your needle is still dropping and moving, have the speedometer cable inspected as well as the speed sensor. One of the two, or even both, could be causing this problem.

~Hope this helps...
