3 MECHANICS CANNOT FIGURE OUT WHY KIA SEDONA HAS NO POWER AND USES TOO MUCH GAS!

Thanks for taking the time to respond....2 mechanics checked the timing and while it was apart the second time we had them replace the timing belt. 2 mechanics also checked the catalytic converters. Multiple scans have revealed nothing... Thanks again

Let us know what you find out, IF you ever do, because this engine normaly has all the power you will ever need! I am out of guesses and that is all we can do. I thought the timing belt was replaced the first time. I still can't figure why the scanner doesn't show anything when reading live data!!

The Kia dealer figured out what was wrong today. When the first shop installed the crankshaft sensor, there's a part that stays on the vehicle that has a small hole and the sensor has a divit and fits in. If it's even a millimeter off, it breaks the crankshaft sprocket. In this case because it was not lined up it created 2 new holes, throwing off the timing of the vehicle. $750 to repair. So, all because of this first shop's mistake I'm out lots of money...wish I had brought it to the Kia dealer to begin with!! Lesson learned!

Well i sure am glade it did not break the crank sprocket! If that had hapened it would have been MUCH worse! Anyway i am also glad you got it fixed. Don't get discouraged by this though, most independent shops are very reliable and up to date with today's auto repair! That being said, i have fixed some dealer mistakes as well. One more thing you may want to check into, there has been some crankshaft pulley bolt berakage on this engine, have fixed a couple myself but i feel sure the dealer installed the newest upgraded componets. Thanks for the response.

Thanks, no I won't get discouraged by local independent shops even though I'm surprised that 3 mechanics could not figure this out. Dealers make mistakes too, it happens. Just glad it's fixed and hope there are no more problems! Really appreciate your time!

I hope everything works out for you with the other shop, seems like they just made an honest mistske like we all do. Thanks for the reply.

We thought so too, but 2 different mechanics checked the cat. converters and the timing. We even had a new timing belt installed - no difference. Thank you for responding

Thanks for responding...I agree, I believe something happened after the installation of the crankshaft sensor since it has never run right since. The Kia dealer finally responded yesterday that possibly it is the sensing blade, which is what the crankshaft sensor works with - or possibly a defective crankshaft sensor (but I wonder why it would even run in that case). Is the sensing blade for the crankshaft the same as the reluctor wheel you are talking about?? Thanks for helping me!

Yes..that the same thing.

To follow up with you....The Kia dealer figured out what was wrong today. When the first shop installed the crankshaft sensor, there's a part that stays on the vehicle that has a small hole and the sensor has a divit and fits in. If it's even a millimeter off, it breaks the crankshaft sprocket. In this case because it was not lined up it created 2 new holes, throwing off the timing of the vehicle. $750 to repair.
